I hope the job system doesn't lock you into that class for that job.

IE I don't mind unlocking monk from Pugilist, but Monks were not always Hand 2 Hand fighters and should be able to flex their specialization onto any weapon once its mastered.

Same for things like Paladin. Paladin can traditionally use Great Swords and Polearms not just Swords and Shields in most final fantasies so I'd hate to have it limited that way. Unlock yes, Use afterwards no.
