Reborn Feature:

I don't see the allure. There's already 19 separate classes to level, including crafters and gatherers. For battle classes, once you've done the main story leveling slows to a crawl due to the XP slowing down due to waiting on FATE pops or doing other less efficient leveling methods.

I'd play Disgaea (which I can't stand) if I wanted to do this.

This would affect people who max out every class and want to level them up again. It's not a bad idea, I've seen other games pull it off, and it would be an alternative to creating a new character.
