There are other options. Cc is a waste cause he is above 100cc already.
Right now I'm testing... Speed. When you put gas first in your team I think he holds better against padme, as the first ability he uses is cooldown increase, and only ahsoka has crit immunity. If rex is first gs's aoe won't be as effective as only sometimes he'll go first.
He will still kill almost anyone.
I'm only considering offense or speed, the other set being health right now, but I suppose crit damage is also good.
