Troubador would be super useful or a necro/conj.
Alchemist for poisons is super good, and they make spells all the way up. Woodworker is good for arrows as well. Provisioner makes food, Carpenter makes repair kits. The rest of them are just kinda, there? I mean it's cool to be able to make spells but it's really easy to get master abilites. At 50 I think I had like full masters sans like two spells within the first like three weeks. And the armor/weapon makers don't make gear that's better than most legendary/fabled gear, so it's good for the start of xpac but the market has more supply than demand quickly.
