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).
Certain locations in World of Warcraft – primarily inns, capital cities, and private instanced zones like your garrison or class order hall – are rest areas. You know you’ve entered one because your character portrait will gain a “Zzz” icon where your level is normally shown, and because you can immediately log out of the game instead of waiting 20 seconds.
As an example, I will take my server values to calculate how many procs you need to make up the price of one Magnetic Mining Pick (40 SS ore, 10 Platinum ore, 15 Expulsoms). Assuming 25g per SS ore, 20g Platinum Ore, and 55x the price of Tidespray linen to craft 1 expulsom in average (got the value from a previous post in this subreddit); 1 Pick is worth 5325g (not counting the elemental flux).
Be cold-blooded about admitting that you've taken a bath on an item. If you bought that sword for 5g, listed it for 10g, and the listing cost is 2g50s each time, after two times it had better sell just to break even. Once you hit that point, don't keep listing it over and over in desperation trying to make something off the AH. D/E it, or vendor it, and move on. Lesson learned. Don't get trapped in the fallacy of sunk costs.
To use it as a bank, figure out how much you want to have on-hand on your character based on how much you normally spend on repairs, food, ammo, etc. and send the rest to the bank alt. The principle here is "Out of sight, out of mind.". Money "you don't have" cannot be spent, requiring you to log out of your character, and then to log into the alt.
YouTuber Oldbess recently uploaded a video about this cool method.  Generally completing the scenario "Deaths of Chromie" will allow you to pick up the item "Time-Lost Wallet" in excess.  You can get it from just killing the mobs or actually completing the scenario in full.  By then end you will have dozens of time lost wallets.  Each wallet awards 50g AND a rare chance at getting the ]bronze proto-whelp[/U] pet.  In the video, this spot was VERY hard for to pull off as it requires a high item level.  With an 809 item level I struggled all throughout the scenario and could not make this spot profitable for the time invested.  The good news is, if you can get it done, the gold you make will be entirely liquidated – the rewards are 50g raw for each wallet turn in.  I suggest you watch it on Oldbess's channel for full details.
-PvP- Completely broken for some classes and I mean broken going from both sides of the spectrum, from classes destroying everyone, to classes that can't even kill another player. It's fairly common for a weak class to lose to a powerful class even if the weak class outgears them by 50+ ilvls. That's how broken PvP is and Blizzard doesn't seem to know what to do to fix it other than do blanket damage nerfs/buffs as those are the only changes we've seen.
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.

Thanks for this guide. In the preparation section, you could add Goblin Gliders which are always super useful. I also recommend picking Northrend Engineering and Draenor Archeology as temporary professions. The first allows the use of the loot-a-rang toy which allows looting movs from a distance. The second one is required to picknsome treasures in Draenor.

There’s a lot of #content in the new expansion. It’s mostly locked behind a variety of gates, some of which players can’t even control. Warfronts are the best example. You might assume joining a Warfront is a simple matter of opening the group finder. Wrong! Warfronts are only accessible for a week at a time. It’s not precisely clear how often that week will come around (it’s based both on a time gate and on the opposing faction gathering resources) but, as of right now, it looks likely to be available just one week out of every four.
Another potion of treasure finding farm that was made extremely popular by the YouTuber Oldbess.  In this spot, you are simply to patrol the entire southen river basin in Twilight Highlands, just around the Verrall Delta area.  The goal of this farm is to kill water elementals for their volatile water, which trends around 50g per drop.  Combine this with the cloth and the treasure chests, and you have a cool  nifty farming spot – thats rarely populated these days.
A cool little pet farm that can take minutes or ages depending on the god of luck.  This spot contains some of the most dense troll spawns in the game, and each has the highest chance to drop the parrot pet thats soo sought after.  On every serve rthis per has  amedian value of about 70,000g so picking one up can be a pretty cool feat.  Like the sprite darter hatchling spot its, a random farming spot that requires alot of RNG to pull off, but if you get it to drop you can make out in spades.  The other drops are miniscule when compared to this spot.
Battle Standard of Coordination: This item gives you 15% bonus XP if you stay within 100 yards, with a 10-minute cooldown. Can be useful if you are grinding in an area or when completing a dungeon. If you plant the banner at the last boss of a random dungeon you will get 15% extra from the bonus XP as well as that XP is awarded when killing the last boss. You need to be friendly with your guild to get this. The easiest way to get it on a new alt, is to buy a Renowned Guild Tabard with you main and send it to your new alt. Now you need to join a guild with the “A Daily Routine” achievement completed. So open the guild finder, if you’re not already part of a guild, and look for a guild with a lot of members since they are more likely to have the achievement, and ask to join. Then buy the Battle Standard of Coordination.
Island expeditions require groups of three players to venture to islands with randomly spawned enemies and piles of AP. The island expedition ends once they collect a certain amount of AP, and they are granted about 300 AP as a reward — unfortunately, players don’t get any of the between 6,000 and 12,000 AP they collect during the expedition. These missions can take anywhere from three to 20 minutes, and never once offer any real challenge or depth.
Alchemy is a crafting profession that can create potions and flasks, as well as some trinkets and mounts. The primary materials used are herbs. For potions and flasks only the Legion crafts have substantial demand as they are the only items that give meaningful performance increases at max level. Old world alchemy recipes that are profitable include Vial of the sands and transmutes.
The most simple thing is TradeSkillMaster. This AddOn shows you quite an amount of information in the items tooltip. In my opinion, DBRegionMarketAvg the best source. It tells me the price, an item was posted on all EU realms in the last 14 days. Why not DBMarket? DBMarket only shows you the items value from your server in the last 14 days. This value often gets manipulated. Some people start to post an item with a 500g value for 500.000 Gold on the auction house for several weaks. As a consequence, DBMarket is rising towards 500.000 Gold.  If you use DBMarket with 100% and post your item for 500.000 Gold, nobody will buy it.
