^ but what i like about those games is that they let you decide what each characters role will be. Plus it's more efficient to play with specific jobs/roles anyway.

For especially later FF's, i like looking at stats and deciding what each character is good at, then putting them in a role that exploits those advantages, whether it be magic, strength, vitality, or spirit. I'd like to see this with XIII, with more choice than say X but allowing you to really customize and make the characters different, a little more than XII.
