Sorry, my 4:20 was pushed back to 7:20 and I just got to thinking...
Wouldn't it be cool if in Titan's animations when he pulls a rock out of the ground, the rock he grabbed actually looked like it came from where he was standing? It's not a game breaking new ability or anything, but would have been a cool addition.
I think (its been a while) in some of the older FF games when using earthquake like spells/Summons the ground that was displaced and shaken was the same as the battlefield.
Obviously I'd rather see some other changes first, and it wouldn't really give me a reason to use Titan for anything other than Earthen Armor (which doesn't even involve ripping a rock up from the ground), but if its easy enough could be interesting.
