Hello !
I've been looking at each profession guide for Legion and lots of them seem really usefull HL !
For me the best are : Alchemy, Inscription, Enchanting, Leatherworking, Engineering...
I really don't know what to take ! What would you recommend me ?
PS : I think it's a good choice to take at least 1 gathering profession if you are missing one or more professions at the begining of your leveling route !
