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. 
Bags: This SHOULD be a no-brainer. The cheap-o version are Netherweave bags, but if you have the gold I recommend you get the largest bags you can afford, since it means you won't have to stop to clean them out as often. In fact, if you have an excess of gold, it's probably not even worth your time to stop and loot mobs that aren't quest objectives. This seems like a small thing, but over the course of 100+ levels, all those clicks to loot add up.
Starting at Level 15, you are able to queue for dungeons with the in-game group finder. You should aim to do this whenever possible while in Restoration specialization, as it is an efficient way to level up while learning your healing kit. In order to understand in-depth how to use this kit, especially at higher levels, check out our rotation page, but we have added a short summary below:
Soloing an instance can be all the more profitable if your character is an enchanter. During any solo instance run, you'll end up with some items which can be sold or traded, and some that are bind-on-pickup. Non-enchanters can only sell these soulbound items to a vendor, but an enchanter can disenchant the bind-on-pickup rare items, and then sell the shard/dust/essence instead of just selling the blue item to a vendor. (A side benefit of selling enchanting materials is that they do not require a deposit to list in the auction house, allowing you to list endlessly until the item sells.)
Now lets get to a "math". You need 10k reputation for a cache. For a daily emissary quest, which gives the rep the fastest way you receive 1.5k reputation. Since the quest needs 4 of the world quests for said faction, lets total them up to 500rep which gives 2k reputation for an emissary cycle. Lets optimistically say that you require 3 minutes to reach a world quest and finish it, totalling at 12minuter per 2k reputation. It would mean that you spend an hour total on a chance to get up to 5k gold. Ofcourse there would be some exceptions to that, such as tortollan quests that need only 3wq, rare quests that give extra rep and more rep in general or for example follower missions for extra rep (but those require resources). But there is also a fact that you might take more than 3 mins to finish a wq which negates that.
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.
