I do Alchemy and Herbalism BIG help since we need alot of mana...and especially healing potions. BUT then there are the talent potions that are a bonus....aka fire and frost damage potions. Then i do first aid and fishing (u can do all 3 but we summon food and drink so dont need cooking) BTW Fishing is a must i think if ur doin alchemy because some of the potions use things lik oily blackmouth and fire finsnappers which are fished.
