You know, if they are going to go in an rework the gameplay a bit like they did with Tactics Ogre Reborn, Cloud is a perfect example of someone who really needs to be reworked. Hell just simple things like making his limit breaks insta-cast or letting them target an enemy and not just squares would make him a much better character. The twins would be another set of characters that need to be retooled.

Other than that, I'm hoping they rebalance the class system a bit. Archers and Dragoons could both use some retooling.
