I'll second that. I suppose this is why IV and IX are so special to me. As much fun as I am having with XII right now, I can't help but wish that the characters had more unique abilities.
In some of the games (VI, VII, VIII) I couldn't help but wonder what the point of having more than 3/4 characters in the game was since they can all pretty much to the same thing minus a few unique abilties.
