As you're leveling, I generally recommend you just follow the natural flow of the progression through each zone. They're laid out fairly reasonably. But don't be afraid to hop around, especially if you're near a quest objective. You shouldn't actually need ALL of the zones listed to reach 62. Pick the ones you like best. It's much more important to simply be as focused as possible and flow from one quest to the next.
This is a VERY GOOD potion of treasure finding farm that generally shocked me when I stumbled upon it.  In this video it's one of the more popular farms – just because it's potential to tap into soo many different markets (especially if you are a skinner).  It takes place at the pit of scales near the foot of the uldum river.  It allows you to not only gather tiny treasure chests faster than any other spot, but also awards an obscene amount of leather.  Just step on the eggs and 5 crocolisk will attach to your character.  Kill them all and start skinning them.  There are 6 egg spawns with very short respawn timers surrounding the area.  You will literally never be waiting for respawns.  Again, skinning is a must to take advantage of this mega spot – and even though, I feel only a handful of farms surpass this one, It's truely my favorite.
Drustvar is far and away the hardest Alliance zone, which is exactly why you want to do it first. If you have legendary items, they’ll still be usable, and if you don’t, this zone will still be easier early on than it will be later. Drustvar is also extremely fast and will let you jump out ahead of your competition in other zones, which means fewer players around to take your quest objectives.

Oct 24 A Return to World of Warcraft: Player Guide So you’ve decided to return to World of Warcraft. Welcome back! There’s just one thing you’ll need before jumping back into the fray—knowledge. To aid you in making your glorious comeback, we’ve compiled some handy information every returning hero should know. Once armed with knowledge, nothing (and no one) will stand in your way. Oct 24

You will have to buy [Mark of Blackrock] or [Mark of Shadowmoon] at the Enchanter's Study with [Secrets of Draenor Enchanting]. These recipes cost 5 Secrets of Draenor Enchanting so you will have to wait 5 days until you can buy one of them. It's worth to wait because with other recipes you get 1 skill point / [Temporal Crystal], while with these you get 5 skill points / [Temporal Crystal].
The next World of Warcraft expansion, Battle for Azeroth, takes the game back to its roots a bit by focusing on the battle between the Horde and the Alliance. Each side will be able to explore three new zones. The Horde will have access to the islands of Zandalar while the Alliance will be able to traverse the island of Kul Tiras. These new areas will reportedly contain "allied races" which players will be able to recruit and eventually play as. 
Level with a pet if you can because it will help keep you safe. If your pet is tanking all of the damage from the enemies you’re fighting, you won’t have to. The other reason is that pets are easier and cheaper to heal than you are. If you don’t have a pet, make sure you know how to use your defensive abilities. You can’t level quickly if you are dying all the time.
If you already have a high level character or a friend willing to give you gold then you can purchase Heirloom items. These items are bound to account and are accessible through the Heirlooms tab using Shift+P. The benefits of these Heirloom items is that they scale with your level keeping your gear up to date without you having to worry about upgrades, and they provide a significant XP bonus.
While enchanting is generally considered expensive to level, you can make a profit with it as soon as you start disenchanting for profit. It is not unlikely that almost any green item in this case will have a buyout price for a lot less than the materials it disenchants into. Likewise, it is lucrative to check the auction house for green items with unpopular suffixes, such as "of the Gorilla," with low starting bids.
Val’sharah is the main WoW Legion zone where you can gather Dreamleaf, being also one of the best zones to skill up Herbalism. In fact, if you’ve just started Legion with your herbalist character, this is the best zone to begin with. Requirements: Minimum character level 100; Herbalism skill 700; Gatherer addon (optional). Where to go: Fly to Lorlathil (54,72) in Val’sharah. What to do: ... Read More »
The last farm on this list, actually I was surprised this farm eluded me for so long.  Generally speaking gnomergan is a huge confusing instance that takes some getting used to but if your a high value transmog farmer this does not scare you.  You can pull the entire instance and get access to a plethora of high value loot such a recipes, world drops, greens and even engineer supplies.  Overall this farm is shadowed by the Diremaul farm and Zulfarrak farm, but is an equal change of scenery with a wild card if you get the hot shot pilots gloves OR the mechbuilders overalls worth 400,000g and 60,000g respectively.  A pretty cool neat farm that noone really mentioned until now.
“I think that there’s a lot of gray in the game and in our world, right,” asked Cobo. “And so I think that tapping into that and making things reflect the complexities of the relationships that we have between these key characters and then the player itself, and having the player be able to experience that from their perspective, is really what is one of the strong connecting hooks of World of Warcraft.”
Warlocks have received new spell effects; all the other classes received new effects in Legion. Male orcs are now able to toggle between the initial hunched posture and standing upright by using a barbershop, but the other races are not able to toggle between two postures.[5] There are new druid forms for the allied races, i.e. a Zandalari troll forms are all dinosaur-based, while the Kul Tiran humans take forms made of wood and bone as their teachings come from the Drust people who populated the land before them rather than the Cenarion Circle.
Guild Banners. The Banner of Cooperation and Battle Standard of Coordination will increase the experience from kills. They both have a 10 minute cooldown, but when you use one, the other is only locked out for 2 minutes. I was very bad about using these, so it might be worth using a macro to drop them on your first attack against an enemy. Keep in mind you must have reputation with your guild before being able to buy these, so new character may have a bit of a wait before picking them up. 

* Financing available is "Equal payments, no interest" for 12 months (unless otherwise stated) and is only available on request, on approved credit and on purchases of $200 or more (excluding gift cards) made with your Triangle credit card at Canadian Tire, Sport Chek and participating Marks and Atmosphere locations. Interest does not accrue during the period of the plan. However, if we do not receive the full minimum due on a statement within 59 days of the date of that statement, or any event of default (other than a payment default) occurs under your Cardmember Agreement, all special payment plans on your account will terminate and (i) you will then be charged interest on the balances outstanding on such plans at the applicable regular annual rate from the day after the date of your next statement, and (ii) the balances outstanding will form part of the balance due on that statement. There is no administration fee charged for entering into a special payments plan. Each month during an equal payments plan you are required to pay in full by the due date that month’s equal payments plan instalment. Any unpaid portion not received by the due date will no longer form part of the equal payments plan and interest will accrue on that amount from the day after the date of your next statement at the applicable regular annual rate.
This achievement requires you to completely explore both Kul’Tiras and Zandalar continents, uncovering and mapping all available regions. You’ll likely uncover most of the zones without even trying, as questing while leveling then later completing World Quests will take you through most every part of both continents. The achievements will let you know which areas you still need to discover, such as “Savagelands,” but that isn’t all too helpful. Just look for any areas which are still unrevealed on your world map.
 Void elf - "Many have sought to harness the corruptive magic of the Void. Most who tried have fallen into madness. Determined to use this power for the good of Azeroth, Alleria Windrunner is the first mortal to succeed at defying the shadow's whispers. Coming to the aid of a group of her kin who nearly gave in to the darkness, Alleria has vowed to train these Void Elves to control the shadows within them and pledge their newfound powers to the Alliance."
Heirlooms can certainly be used with our guides! You may find yourself getting ahead of the guide. If you start doing gray quests, just skip ahead to a later zone. The guide is just that - a *GUIDE* not a rule, as many people seem to think. Feel free to skip parts! Watch out for quest chains, though, especially in the last part of the 50-60 section. Hopefully we'll have some awesome features in our new addon that will make it easier to skip around!
Jewelcrafting is a crafting profession that revolves around gems. You prospect various ores turning them into gems and cut the gems. The cut gems can be added to socketed items. In addition you can craft rings that can either be disenchanted or sold as gearr. The Legion epic and rare gems and rings all sell very well. The jewelcrafting panther mounts are the best old world recipes.

At 98 you have the option to drop what you're doing and return to your capitol city to start the quest for your Legion Artifact weapon. However, I do not believe this is necessary to do right away unless you're struggling with kill speed in your current gear. I would recommend waiting for a natural pause, such as hearthing to repair and clear your bags. From 100 to 107 you won't even really fight mobs that often; only just enough to clear the way to any treasure you need to pick up.
There is an alternative really cheap method, but only Blood Elves can benefit from it. Due to their Racial Ability it allows them to gain ten free skill ups by converting a Large Prismatic Shard into three Small Prismatic Shards and back again. Only the conversion from one Large Prismatic Shard to three Small Prismatic Shards is effected by this. Therefore, you will only have the chance to gain skill ups half of the time (since the other half of the time you'll be converting back to three Small Prismatic Shards). This can make for a fairly lengthy session in gaining your ten free levels.
3. When messaging these players, it is important to remember that they too are people and are looking for emotional connections in their social lives. Having a name without mart or sell is only the first step. Do not approach them and immediately spam them with "need gold plz"! Say hello, ask them how their day is going, etc. After you establish this basic interaction, most will ask you how you are doing. The most successful phrase I have seen has been "I am doing well thanks! I am new to this game but I like the people here very much. I saw I needed to buy skills but I'm not quite sure how to make money. Would you mind helping me please?".
This is not to say that you should never buy gear. Having equipment that is reasonably current while leveling allows you to kill enemies faster, and die less often in the process. Faster leveling = sooner to higher levels (where the real money is to be made). Likewise, death = loss of time. And, as we all know, "Time is money, friend!" So, players should not hesitate to make well-considered equipment acquisitions during their leveling up, but only if they represent a substantial improvement over their existing equipment and if the price is right. Try to find good deals. It should go without saying that you should never purchase any equipment from vendors; always use the Auction House. Look several levels above and below your own for bargains. Don't buy items that you won't hold onto for at least 4-5 levels. And don't always use the buyout option at the AH. Some of the best deals come from bidding and being patient - it'll be two days at the most. Of course, if you play too hard you may have surpassed that weapon by the time you win it. In which case, you may want to auction it again. If you know there's an item that would be great for you, say, five levels from now, keep your eye out for it and bid on it, several times if need be. When you get it, stuff it away for later. That's why you have a bank alt.

There's a good chance you can buy the raw materials for 25% - 75% of the going rate of the finished item, or mine them for free. The fee for an 8 hour auction is only 1 silver, so you can afford to re-auction rods that don't sell the first time. Be careful of making too many rods or other parts of a kind at once, though, as you may get stuck with them for a long time when others produce the same item and set a cheaper price to it.
On my server there's a big shortage of Primal Air. I've tried farming it in the past using supposedly the best spot(s), but it was honestly horrible. After looking at the Wowhead for Primal Air I noticed there's actually a transmute recipe for Primal Water to Air. I will say as a warning that it apparently does have a 1 day CD like a lot of transmutes, so for some people it might not be worth the time. But at least on my server, there's not 1 Primal Air on the AH and I know that it's a constant shortage, so at the moment I could make a lot of profit just doing my daily CD for this after getting the recipe. To get the recipe you do have to be revered with the Cenarion Expedition from TBC, and there's guides on Wowhead for grinding out that rep as well. I'd recommend checking the stock of Primal Air on The Undermine Journal for your server, and if it's relatively low and you have at least 1 alchemist, go for it. It could be a decent way of making a little more passive gold, just transmuting one Primal to another. I'm probably actually gonna start rolling another alchemist at some point, and this discovery has definitely prodded me in that direction as doing this transmute won't interfere with other TBC transmutes, because there aren't default TBC transmutes as far as I'm aware.
