going into my second game i don't have the play test data to support the claim, but i think capturing is a bit too strong in this game. Rescue missions are hard to come by and capturing seems really easy. don't get me wrong; i love the mechanic. In the PC version it really added flavor and it does so here. Its just really a big blow to the rebels and it seems a bit too easy.
I actually think there should be a starting (the ones that go back to hand) mission that could attempt to free a leader. I'm not sure, though. Its just a hunch. time will tell but one thing is for sure; if I'm doing stuff at a imp system, I'm bringing backup.
