I've shot down lots of bombers with no one in them, many times on a long flight ppl had to go do something and didn't get back in time. But that was in AH2.
I don't see long bomber flights in AH3, they're pretty much suicidal with so few planes in the air. Maybe with AI a lone strat bombing raid (if the strat isn't right next door to the base like in the spiral map) wouldn't be a suicide.
It might even help the bomb and bail problem if the pilot knew he could maneuver and have an AI gunner. That he wasn't just there to be pwned.
I say we need to be thinking about new players, and new players WILL WANT AI GUNNERS, at least until they are experts like you all.
I SAY AGAIN, why not a check box to choose between the features, check it if you don't want AI gunners and leave it be if you want them????
