They missed out on the 'consumables' class crafter.
Uldah has Alch for pots, Limsa has Culi for food, Gridania didn't get one.

If I was going to dream big I'd want a 'Ranger' style crafting class that specialized in making camps. Anything from a simple fire to a full on forward camp with facilities. It could be tied in to the exploratory missions. Put up a camp where you can repair, call a retainer, get rest exper, generate buffs, void aggro, you name it. They would be the crafting arm of frontiersman.
