Most BfA Alchemy recipes have 3 ranks. Rank 2 reduce the materials required to create a recipe, and Rank 3 have a chance to create multiple potions/flask etc. Higher rank recipes also give skill points much longer, so it will be a lot cheaper to level Alchemy if you first get Revered with the new BfA factions, because you can use cheaper recipes for longer.
A: The amount of time it takes to receive your gold after putting a Token up for sale depends on a variety of factors, including the current supply and demand. When you list a Token, you’ll be quoted an estimated time based on the current Token supply and the rate of recent transactions, but the actual amount of time it takes to sell is likely to vary (note that Tokens do not expire). In most cases, Tokens are sold in the order in which they were put up for sale; however, there are some exceptions to this, such as when a Token purchase is undergoing verification.
Another dungeon farm, this time in Uldum, Tol'Vir trash mobs drop loads of embersilk cloth. Stacks of this tend to sell for a tidy profit, though prices vary depending on the realm. A typical clear of the dungeon takes about 5 minutes, netting about 7.5k per hour in cloth, vendor trash, and various other drops like mats and BoEs. Pick up a Potion of Treasure Finding and farm to your heart's content! It's just as profitable on normal mode as heroic, too, making farming all the quicker and easier.
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.
Congratulations on reaching Level 120! There are a myriad of new things to do. The first thing you should do is head to your faction hub ship where you have been doing your mission table quests and footholds to pick up and complete the quests necessary to unlock World Quests. World Quests will provide you an opportunity to grind reputation levels, acquire gear, and gather Azerite. There are tons of new things to do that we will cover in our Level 120 Battle Guide found here: Level 120 Battle Guide
