OK, lets consider two players: you in your set of three B17Gs trying to bomb my town and me in my Spit IX trying to stop you. You have 39 guns to fire at me. I have essentially two to fire at you (the 0.303s won't do much of anything). If you shoot off my wing I'm done. If I shoot off your wing you've got two bombers and 26 guns left. Now you want to make those odds even worse?
