Also here's an easy analogy of the situation:

I want to be a Musketeer, the guild is already in the game, the gun models are already in the game, but I can't be one because Musketeer hasn't been added yet, so I have to wait untill it is.

Crafters want a personal chocobo, chocobos will be in 1.19, but they can't get one yet without a battle class because chocobo breeder hasn't been added yet, so they have to wait untill it is.

That sounds pretty reasonable, yes?
