Alpha Strike also works against shield regenerating Rebels, too.
Still, I do want to run Dengar really bad. I never liked fat turrets before, but I want to run him.
You could run him as a torpedo boat. Probably not the most efficient way to do it, but it's an option. I'm super excited for Gamma Squadron Veterans because with Homing Missiles and a whatever supporting stuff you think is best (Deadeye, Crack Shot, LRS, GC, etc.), a couple of bombers should be the antithesis of Rebel Regen. You should be able to keep them running or make them dead.
