Restricted Cast, who would you pick?

I wasn't really thinking character plot rewrites... more along the lines of downplaying their roles in the game and making them non-combat characters.

For instance, Edgar is the king of Figaro. He's got an entire country to lead; he can't be running around in caves with some witch. Setzer can pilot and maintain an airship without going into battle. That sort of thing.

Your breakdown of action commands is really good, though. I particularly like what you described for Sabin.
