Current Best Gold Making Professions

[Jabberie]

you only get back things you get from the quest since you literally cannot do a quest a second time. Some professions get their stuff randomly from kills etc so you lose those. Not to mention, you do not get back the older stuff or your skill level. But the skill level, as I said, doesn't matter for Legion stuff.

Ranks of which there are 3, just reduce the materials required pretty much. Alchemy lets you get procs at rank 3.
Gathering just gets more and more per rank.

Enchanting level 1 DE is confined to legion stuff though. Sorry for that confusion. You get skill ups for DE'ing legion stuff as well. not many.

Cooking is done through work orders. Give Nomi 5 mats, he does a research and has a chance to give you a recipe.

There are 3 variants of each food type. Again with 3 ranks each, give you more per craft.
Food is rather expensive, as is fish/meat. some of the foods need herb and even JC parts.

Fishing has it's own Artifact rod as well for it's own cool story line.
