A common mistake of new players is to upgrade their gear at every opportunity, paying for a new piece even if it will only add one or two new stat points over an existing item. Likewise, investing in headgear, neckwear, trinkets, and rings at the earliest available levels can also consume valuable cash. While it might seem foolish to leave an available slot empty, you will eventually find something to fill it. Blizzard will see to it via the quest rewards you'll get along the way. In the mean time, the 1 or more you save will serve you well if you invest it wisely. The bottom line is that one can easily level all the way to the maximum relying on just quest/drop greens. The gear you get from regular questing can help you perform well in dungeons, which gets you even better equipment.
First of all, the value of transmog is decided by rarity and how they look. Some items like Minenarbeithut der Tiefen or Pendel der Verdammnis (they can drop in Uldaman) are worth millions of gold. They are worth so much, because they have a really small chance to drop. Other items are bought well because they look good. Best example in this case is the Glorious set, its legplates Glorreichen Beinplatte reach a 100.000 Gold value easily.
These books cost 1.000 Gold each and are sold from your BfA gathering profession trainer. As soon as you re-learned your farming profession, use this book and you will get back all of your lost Battle for Azeroth gathering ranks. Your gathering skill remains reset at 1, but you don’t have to care about that since you have your ranks back – thats literally all that matters.
ElvUI is a complete replacement for the default User Interface. Not only is this a popular AddOn among top players, but we here at Icy Veins use it for all our characters. ElvUI eliminates most of the inefficiencies of the Blizzard interface, which are many and varied. It is extremely user friendly, and takes very little time to set up and master. It also comes already furnished with almost everything you need; unit frames, raid frames, minimap, buffs and debuffs, and much more. You can easily unlock and drag all the components around so your UI will look exactly the way you want it to. ElvUI is clean, easy to use, and a great starting point for your UI.
This is an infinte farming spot that takes place just east of maraudon.   It requires you to stand in a specific spot which will allow you to kill all the slitherblade naga that surround the river.  This spot is generally a GREAT spot since the mobs respawn instantly after death.  You will get an obscene amount of silk, wool, greens, and low level patterns.  It's one of the only remaining infinite respawn farms left in the game.
Once you download the addons from the website to the downloads folder, you can right-click on the compressed (zipped) addon folders, and select "extract all". After that, you go to Windows folder, click Program Files (x86), and scroll down until you see World of Warcraft. Then click on Interface, and then select "Addons". After that, select "extract all" to transfer unzipped addon files to that "addons" folder.
This is also the reason why when I read in WoW forums of people skipping guide sections, due to being too low level I'm not agree and start ranting about it: it'll be a mess syncronizing with the guide and I've seen many people complaining about missing quests or accusing the guide for being innacurate, but not realizing that was their fault since they're skipping and missing a lot of quest chain requirement. Of course this apply if you're following a guide, believe me, it's very frustrating when you remain stuck in a guide section due to the reasons I've mentioned, more than doing grey quests (but they allow to be perfectly in sync with the guide) and goiing here and there to get the pre-requisite quests.
The idea of the expansion came up after the heroes of Azeroth dealt with so much external threats like the Burning Legion. In their own words, "so when we talk about what's the biggest threat in this world, is it the titan or is it the dwarf paladin that put a hammer in that titan's head"? As such, the enemy (at least during the early parts of the scenario) will be the opposite faction, a "vast army of world-destroying forces".[4]
This is by no means a complete strategy, just a bit of insight into how I believe many approach transmog incorrectly and burn themselves out on it before they can succeed. There are better ways to do this, and you're free to pump as much time as you'd like into it to try and improve the results. Whatever the case, just make sure you're enjoying yourself, because it is that much easier to stick to when it's fun.
“In searching for inspiration for how that might unfold, classic RTS roots felt like the perfect place to turn,” said Hazzikostas. He later explained that your first job will be to get your team's base fully-functional which will require you to gather resources such as "lumber or gold" to upgrade town halls. You'll also need to clear supply lines of foes in order to allow "peons to do their thing."

For example, the Azure Whelpling belongs to the Dragonkin family. However, it has Beast, Magic, and Elemental abilities in addition to a Dragonkin attack. Different attacks are strong and weak against different family types. Having a diverse spell selection might increase your chances of being prepared with a strong attack against an opposing team.
Crafting is the art of buying materials and turning them into other materials or finished products that you can sell on the Auction house for a profit. It is one of the most consistent gold making methods in the game, but generally requires you to bind up some amount of capital in your inventory in the form of materials and finished items before they sell.

Dugi’s leveling guide is the leveling addon I’ve always used to level as fast as possible. It will show you where to go and what to do in-game, speeding up the leveling process. This is optional though, as the game already does a pretty good job at showing you where to go at all times. The addon does, however, come with a couple of other nice features and perks.
The entire Jade Forst is our farming spot for this one.  Literally, the entire Jade Forest.  The Jade Forest is crawling with porqupines and if you have a mage character, each one of them has chance to drop the polymorph porqupine tome.  Which is excellent, because these tomes have a selling point of 13,000g across the board. They are really easy to get, and noone really pays attention to these spots.  Try it if you like, I was able to get 2 on video, and have already sold one of them.  
That’s because armor of higher level has higher Azerite power requirements than lower level armor. That means a shiny new piece of Epic gear will have better stats but, unless you’ve been diligent about your Azerite power grind, won’t have as many traits unlocked. You lose options as you earn better gear. Eventually, you’ll grind out enough Azerite to earn those traits back, but you’re left with limited customization until then.
It seemed like the Horde players at BlizzCon sat divided during the opening ceremony Before the show started, players cheered for Sylvanas Windrunner, the current, evil(-ish) warchief of the Horde, when her picture showed up on screen. But when the Lost Honor cinematic played and Saurfang talked about “wanting his Horde back,” the audience had a massive, excited reaction.
Island Expeditions are three-man scenarios that pit the team against three enemies using what Blizzard calls “advanced A.I.” That means the enemies will act more like players, pursuing goals proactively and filling class roles. The expeditions take inspiration from action RPGs, with randomized areas that mix up the experience each time. Players’ main goal will be obtaining resources more quickly than their foes, and expeditions should last 15 to 20 minutes. While primarily meant for PvE, there is a PvP mode that replaces the opposing A.I. with teams from the enemy faction.

Leatherworking is a crafting profession that uses various leathers obtained from skinning to craft leather and mail armor. You can make gold shuffling leather into enchanting materials through the rank 3 bracer recipes. Battlebound for Stormscale and Warhide for Stonehide Leather. The other main market for Leatherworking is crafting the item level 850 gear. I find that both Dreadleather and Gravenscale gear sells very well.

I highly recommend actually staying in the 20-60 range zones until you ding 62. The reason for this is that despite getting a slight penalty in experience for being over-level, the advantage of having flight will more than offset this. That, and WOTLK and TBC zones are the slowest part of the leveling process. Minimizing your time there as much as possible is worthwhile.
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.

Azeroth paid a terrible price to end the apocalyptic march of the Legion’s crusade—but even as the world’s wounds are tended, it is the shattered trust between the Alliance and Horde that may prove hardest to mend. As this age-old conflict reignites, gather your allies and champion your faction’s cause—for Azeroth’s future will be forged in the fires of war.
Isle of Quel'Danas: Special mention. At lvl 70 you can start doing the dailies here. Despite not being able to fly, the quest density is VERY high. I recommend hitting this every reset if you spend more than 24 hours REAL time(not /played)in the 70-80 level range. In fact, if you're doing a monk and only logging in once each day anyway, IQD WILL be your best exp/h for this level range.

Skinning is the third gathering profession and it is very different from the other two. It works by skinning the dead bodies of animals with skins. You need to both kill the mob and then gather the body. Your main customers will be leatherworkers. Skinning in Legion is very good and gives a large amount of Blood of Sargeras. I suggest pairing this with a crafting profession that can unload a lot of bloods, like Alchemy or enchanting. For an overview of the best farming spots in Legion you can check out this guide by hikons or this one by WTBGold guides.

If i start on a new realms, I am farming a lot of transmog from classic and Burning Crusade Dungeons and Raids. In the beginning, i start to post them if they have at least a DBRegionMarketAvg (Average value of an item on all EU realms of the last 14 days) of 500 Gold. All the other items get vendored. The time you hit a stock of 1000 Items, my value treshold raises to around 2.500 Gold. All the items below that value get vendored aswell. Newly farmed items that are above these treshold will be listed. Why? If I start over somewhere, I want to get a certain amount of gold quickly. Cheap items are great for that. Later on, to save time, Quality is better than quantity. As mentioned above, re-posting the items on the auction house takes quite a bit of time. At this point, I can recommend you the TradeSkillMaster AddOn, it makes your auction house work really a hell of a lot easier.
