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.
The leveling guides on my site are essentially speed leveling guides.  My leveling guides are the same guides I use myself to speedrun to 60 on new servers to get 60 server first.  I list many occasions where I tell the player to "die on purpose" to go faster.  I tell the player to skip certain quests, because some quests are just not worth the time/XP.  I list tricks and shortcuts to go faster so you can reach level 60 much quicker.  I am still constantly going through them over and over again perfecting the guides to make them faster and easier to follow.  For the most part, the guide can be followed without the need from other player's help, as the whole guide was made from a solo run anyways.  Although I do list quests that can optionally be done if you have a group.
Changes were also made to levelling in earlier content with Legion's 7.3.5 patch. The level-scaling tech introduced in Legion not only be continued in the new continents of Kul Tiras and Zandalar, but was also be applied to content from prior expansions, allowing larger level brackets for lower level zones. Further, as previous expansions are now included in the base game, the level ranges for those expansions are now broadened, allowing players to spend more time leveling in preferred expansions and avoid others entirely. Some examples include a zone like Westfall having its level bracket (at 10–15 as of Legion) increased to 10–60, whilst continents such as Outland and Northrend sharing a 60–80 level bracket. The aim of this change is to encourage more player choice whilst levelling and to allow players to experience the full story of a particular zone without overlevelling the relevant quests.
This was a farming spot that I made vastly popular on YouTube sometime last year.  It is my FAVORITE farming spot of that era, simply becuase it was an old world farming spot that allowed you to hit almost 3 different markets.  With this spot you can get cloths:  Felcloth, runecloth, and mageweave. Herbs:  Goldthorn, ghost mushroom, goldclover, and fadeleaf.  World drops: rich purple shirt.  AND a plethora of transmog from a single run.  I literally had some pulls where I came out with 17,000g in item value for 10 minutes of farming.  It was insane – actually it still is.  Anyway If you have a druid or monk, then this is an awesome farm to hit ESPECIALLY if you are on a high populated server.  Generally just pull the entire instance, and circle it back around the front.  Mega gold to be made here.
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.
101+ At this point you'll start taking a penalty on quest/bonus objective experience for every level past 100. Treasures, however, remain worth their full value all the way through level 105, at which point they'll be worth something like 15% less, and then another 15% more when you ding 106. I recommend that you stop questing/gathering entirely, and collect all the treasures you can stomach, only avoiding any annoying to reach ones inside caves or behind elites/rares(where scaling does bizarro things).
The goblins of the Steamweedle cartel have set up several neutral auction houses about Azeroth. Gadgetzan, Booty Bay, and Everlook all house neutral auction houses. The neutral is useful for making money, as commodities that Alliance players can get easily can be sold at a cheap price to Horde players (or vice versa), and then sold at a higher price at a major city.
Inscription is a very strong gold making profession. It utilises herbs and turn them into pigments for inks. The main outputs are glyphs that give cosmetic effects for your character. You can also craft trinkets that are upgradable with obliterum and Tome of The Tranquil Mind. As with Jewelcrafting you can make gold just by milling herbs. The glyphs are generally profitable, even though competition is usually high. The Darkmoon Deck trinkets have been amazing and so can Tome of the Tranquil Mind be.
Skinning is both highly profitable and convenient, in that you will be skinning the monsters that you're already killing as you level. A skinner starts by collecting relatively worthless ruined leather scraps, but soon moves on to light leather, which can be sold for a good profit. An excellent way to farm leather is to skin the kills of other players, especially if you are following along in the wake of a group. However, do wait to start skinning until it's clear that the other player has abandoned the kill. Don't assume that the other player doesn't skin just because they are not a leather-wearer, for example. Note that your chances of getting a better grade of leather increases with your experience; it is possible, though rare, to get light leather from rabbits. Higher grades of leather yield higher profits. A skinner/miner has potent earning power through the auction house, but often runs out of inventory space.

Nov 9 Where to begin with healing? Since I began playing I've only done DPS, and starting to just generally get burned out on it. I decided I wanted to try to level a Healer, but in no MMO to date have I ever actually played a healer. For a novice healer, what class would be good for mostly PVE content (Super guildless across all toons so not expecting to heal outside of LFD/LFR for awhile) with some battlegrounds when I max out. Note: My PC isn't entirely enjoying when I use too many add ons for some reason, so will not be using any of the healing addons. Do take this into account.Satus8 Nov 9
Excess Potion of Accelerated Learning: Acquired in your Garrison (part of the Warlords of Draenor expansion), this gives you a 20-percent bonus to experience from killing monsters and finishing quests. It lasts one hour, but you can buy it multiple times and use it back-to-back. Alliance players buy it from Sergeant Crowler, horde players buy it from Sergeant Grimjaw. Does not work above level 99.
Note that these general principles do not apply to blue or purple items. If you are a first-time player, there is absolutely no reason to purchase these items. None. Sub-80 rare and epic items are only for the alts or twinks of established players that have money to waste (because that's what it is) by showing off their Staff of Jordan (or whatever). Blues and purples are completely cost-ineffective for first-time characters. Within a few levels, you will find green gear that is roughly comparable, or you'll get better blues from instance runs at the same level. So, do not buy these items, under any circumstances, if you are a first-time character (no matter how cool they look). And even if you're reasonably well-off financially, think twice. This is especially true as your character gets closer to levels 58 and 68. Even the most basic quest-reward gear in Outland will have substantially better stats than anything you can buy off the AH for a level 56 character. The same is true of Northrend gear at level 68 vis-a-vis the stuff you'll get in Outland at level 68. As such, smart players stop making AH gear purchases by about level 54 or so, and then just gut it out until level 58. The same is true at levels 64-68. Within the first several quests in Hellfire and/or Northrend you'll have replaced half of your gear in any case, guaranteed.

XP Potions: The Elixir of Rapid Mind and Elixir of Ancient Knowledge no longer drop. They can be bought on the AH still but are way to expensive for it to be worth it. The Excess Potion of Accelerated learning is available from your garrison quartermaster but only works for level 91 to 99. As of Patch 8.1 you can also buy the 10% XP Potion Draught of Ten Lands.

TSM has a very steep learning curve, as it is a total profession framework. It does not hold your hand, and requires a lot of setup. Luckily you can import settings from other players and there are a ton of settings out there. I have published most of my settings in my pastebin here. You can also check out Sheyrahs. If you want to learn it from the ground up I suggest one of the following guides: PhatLewts, Sheyrah, WTBGold.

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.

Battle for Azeroth also includes a new legendary neck piece called the Heart of Azeroth. This neck piece will allow players to unlock new abilities that are directly tied to their armor. This system sounds very similar to the one that Blizzard implemented in Legion that allowed players to build upon existing weapons via in-game artifacts. Finally, Battle for Azeroth will raise the current level cap to 120 and will include a feature that allows players to buy a boost up to level 110 should they wish to do so. We can't wait to see who hits the new cap first. 

Nov 9 How to start getting legion artifact weapon? I have no idea where to begin or what the quest line is called. EDIT: I got the fangs of the ashamane and continued 50 quests ahead and I have STILL not found any options on changing my feral form with the weapon equipped. EDIT AgaIN: Okay apparently i'm glitched because i watched a youtube video and you're supposed to get the first skin by default simply for equipping the fangs immediately after turning in the quest. Any suggestions of fixing this annoying glitch? EDIT: I FIXED IT! i had to click a locked skin option... then clock back to the default which was already highlighted... "click the wrong thing before the right thing will work"Daunt5 Nov 9
Do people not run these anymore? i've been keeping an eye out including making a group myself but used to be popular leading up to bfa but now there are no groups and i've tried the lfg in the tsm discord but not a bite yet, was wondering if people still do 5 mans of it as it's still pretty profitable at least on my server, thanks in advance
Profit is only created if you make sure your costs are less than your earnings. This is not so much an issue for gatherers who simply trade in some time and effort to gain their wares, but for production professions, this must be kept in mind. Many high-end items that sell well require materials that cannot be provided by the gathering profession normally paired with your production profession. To craft these items, purchasing the raw material from the AH or another player becomes necessary. You must keep record of how much you spent to obtain these materials, or else you may price the finished product inaccurately, either too low that you sell it at a loss, or too high that you can't sell it all.
From “The Burning Crusade” expansion, weapons like Klinge der Zauberei, Die Nachtklinge and recipes for different weapons are really valuable. The best example is Pläne: Teufelsstahlangschwert, worth 500.000+ Gold. These items are World Drops, you can find them in all raids and dungeons. I don’t know any Open World Drops, but that does not mean there are none. Another great transmog source are world bosses and rare spawns on Outland.
