Include a maximum counter for how many times a signature beam has been used. For example I fire Final Flash the counter goes up +1 and the counter would show (1/X) X being the max # (would depend on type of beam). If someone hit the max # of beams they could fire. It would take a certain amount of time for the counter to go back -1 so they could use it again (say 30 secs or a min).
Another idea being that every time someone uses a signature beam the speed of the beam is reduced so you have time to try to counter. Or the speed of the beam could be determined by the person's relative PL.
Just a thought :/
