These are the classes I would like to see
Enchanter: Being able to enchant gear and weapons
Materiacraft - Able to craft materia (but I would like them to had materia slots into almost every piece of gear) people have not realized that materia can and does make a difference in the gear.
Scribe or add scrolls to to alchemy - scrolls to like run speed faster, or exp increase does like that. and could add enchants onto a magic scroll to be sold on MB
Alchemy - I would like a buff to this class, whats the point of a potion class if its mostly useless. (give us enemies that if we soloed we'd have to use this stuff), and I miss going into fights and the leaders be like "I hope you didn't forget you poison pots or antidotes"
I think this game needs some of these crafts. ANd they need to make some of the crafts useful. Not in just making gear, that doesn't even matter unless you REALLY want to do a certain dungeon and cant wait but most definitely materiacraft, and also putting materia slots on all higher level ilvled items like AF gear and weathered gear
