You know, I was looking up what the earliest level you can hit max damage with Terra was, just to see what kind of HP she would have at the time. Depending, Sabin wouldn't even need to hit for max. Without any tweaking or focusing, Bum Rush can easilly hit for 5K+ when you get it.

Then I remembered this is a god damn cage match. There are no mechanics that will come into play here. FF VI has no mechanics that come into play in the realm of a cage. FF VI wasn't a game designed to pit player against player. No amount of arguing mechanics will make any sense because of this.
