I would prefer a Job System like in FF1 or maybe like in FF5. Just that you choose your job and by leveling up you learn your abilities. Plus you can switch weapons when necessary. Or like I said from FF1, with the clan idea. You get certain charachters and they are for example a Beast Master, then he cannot be anything else. It would ask more from your stragety. Cause you then really must plan everything. I like the clan-idea, so that they must keep. But what if they just keep their Jobs and cannot become anything else
