Junctioning, the Sphere Grid and Materia make it pretty easy to give characters de facto superpowers. A lot of the characters' in-game antics are superhuman even without abusing the battle system: punching giant robots in the face, suplexing a train, leaping or falling impossible distances, defeating an army tank with a sword, that kind of thing.

If anything, I'd like to see a Final Fantasy where the characters' strength is a little more down-to-earth. I like rooting for the underdog, and it's great to see heroes triumphing through sheer dedication, determination and ingenuity rather than by unstoppable martial might.
