Really, this is my biggest problem with the combat in this game, all the unnecessary buttons and keybinds i need to play.
here is a great example of my Gunblade.
When you control Thancred during the Ran'jit fight, he has ONE button for all three attacks, but why can't MY character have the same thing?
This would immediately open up ~5 slots of key-binds in need for nothing but to chain a combo.
Please implement this in the game for all jobs that have combo chains, it is already in the game but only for story fights for what ever reason. It was the same for Hien, when you controlled him against Zenos.
