Lets throw in 4bz. Two vs five ships. 13hp lost on Chewbo and 33hp lost on 4bz (2b-1hp each and 1z-1hp remain). This seems justified/warranted?
Fair point - you knock out 2 B-wings and have the other ships on the ropes, ready to fall if you just had one more round.
I can see where that would be frustrating.
