I think what they should do is adopt phantasy star online's mag ability system. Make it so that everyone has their own limit gauge, that build both in and out of parties. and when 2 or more party members use their limit breaks within a time frame of each other, enhanced effects occur, maybe even entirely new limit breaks occurring allowing certain combinations to add even more depth and strategy into their use.

The current system just doesn't seem like its going to work too well for a western audience(we're selfish jerks). Good thing most people don't know how to use them. once they do, its really going to be a shit show.
