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

[Focant]

You're assuming far too much. You act as if we have real details regarding the job system other than it gives new skills and has a class requirement to unlock jobs. Also, the job system is built upon the class system. It doesn't really make sense to assume that it will run completely independent of what is already in place, a system that defines classes by the weapon being used. You seem to think the job system will some how supersede the class system, working beyond and apart from it. As a foundation though the class system will naturally impart restrictions upon the job system.

I don't understand why we would have a basic system defined by weapon only to have that rule thrown out the window upon the use of the job system which is layered upon it. To use any weapon on any job when the class used to unlock said job doesn't possess such freedom just doesn't make sense to me and seems to fly in the face of the entire idea of the job system, one that allows specialization and rigidity for party situations.
