Okay, collisions can be a biatch, especiacly when the enemy loses a wing in a HO, and decides to ram you. But the check 6... ive complained a lot about it, because you can see your guy is in trouble. Whenever I see a guy, and i even think hes got a hostile behind him, I send a check 6, because hes on my side, and any kills help me too. If you see it, you should call it. Plain and simple. But if you dont see it thats okay. What i hate is when you get shot down because theres a friendly behind you, who wants you to keep focussing on the hostile your shooting, so the enemy whos chasing you, gives your guy an easy kill. Using a friendly as bait (Without telling him) is the most.... i dont even think theres a word this bad... you can do. My .02, call it if you see it. If you dont see it, not your problem.
