The issue with that though is you go to 0 every death, whereas for a scoundrel, you are back at full energy, so it is a bit different.
I am 100% against giving it a cooldown for scoundrels. I would not support it in any way. I like the ability, I use it a lot on my own scoundrel. My only issue is that I feel it should drop the ball in huttball when it is used.
The opening of a match is the only time its really much of an advantage at all. It doesn't matter that they can spam it mid match. They still aren't the best ball carriers.
