EXCEPTION: If you have Mining and only use Jewelcrafting to craft stone statues (for additional in-combat healing), then this may be a useful tradeskill. However, like Engineering above, it should not be a leveling focus and should only be used to assist with power leveling. Doing any more than this will become costly and should not be undertaken during the power-leveling process.
Fourth, beginning in Mists of Pandaria with the Halfhill farm, and continuing in Warlords of Draenor with various garrison buildings that produced resources, Blizzard has been making trade goods more plentiful and easier to obtain. In Legion, herbs, fish and enchanting materials were so abundant that a very small population of gatherers could supply more raw materials than the economy could consume.
Heirlooms. At the bare minimum you make sure all the armor pieces upgraded to 110, since this is the lion's share of your experience increase. Neck and Ring upgrades are secondary, but still important due to being able to enchant them. Trinkets can't be enchanted, but you'll want them at max as well, if only to save time by not having to worry about replacing them as you level.
While the expansion kicks off with heavy references and scenes of this war, leveling through the Horde side of the new content it barely came up again. Except for all the times I had to mine Azerite to make sure my faction was the leader in the Azeroth version of a nuclear arms race. The Alliance side of things had some heavier references to to the war, at least in the portions I played, with one scenario in Stormsong Valley where a fleet of Horde aggressors bombed a town.
I personally like it but I have healed for 11 years. This will actually be the first xpac where I actually main a DPS (UDK) ever in my history of WoW. The thing I actually really like about pally is they have an Azerite trait that gives the whole group a mini stampeding roar whenever you use golden pony. That is a great utility for a class to have. If I decide to not do UDK I will be doing HPal because it’s the one healer I have never mained.
In 2015, Blizzard started letting players buy gold from each other using WoW Tokens, to try to control the process and mitigate damage. “Time is money, friend — but sometimes one is harder to come by than the other,” Blizzard says on the official page. “Now World of Warcraft players can use the WoW Token in exchange for game time or Battle.net Balance!”
