Please do not lock Jobs to the Weapon Class that unlocks them.

[Physic]

the jobs can greatly limit cutomization and enhance uniqueness without being class specific.

BLM trait, enhanced offensive magic by 15%
BLM skills Xmagic, mana pool, focused spell (increases recast time and dmg)
cross class limits, certain buff skills, and all cures X

just that alone would totally limit and define a role, regardless of weather you were conjurer or thaumaturge

you can do similar things with any job role, and apply it to most classes that would be likely to use it.

These and the things Sorel mentioned are all things I was concerned about :/

We'll Get jobs yay, but they will end up being bastards of the past incarnations of themselves instead of being true nostalgia.
