Actually, buff guns need to have each gun to have its own AI.
This super-convergance crap is screwing up buffs. I fly buff, I feel bad when I single-ping a fighter. I fly fighter and pray to god that the gunner isnt watching me when I do my high-angle hi speed non-6 approach.
I'd say to give EACH buff gun the AI the field ack has and let a human gunner take control of any gun they want and/or allow full human gunners.
AW with its full human gunners has the buffs "right". They eat a good amount of lead to go down, their full human crew is a pain to deal with (but is realistic and fun) and there is little chance for a SINGLE, lone wolf buff to go against 4 fighters, because in AH a single buff has a good chance of shooting down 3 or 4 attackers with no problem.
My point is, if I, as a fighter have to be FORCED to resort to tricking the single buff gunner into a situation where he cant see me or cant switch to the right gun position in time and/or get a number of my fellow fighters to bring down ONE damn bomber I want it to be fair and make the BUFF guy to bring escorts with him OR fly in formation with other buffs.
A couple of nights ago, a group of 5 Lancasters in formation gave me HEADACHES when trying to attack them. Lanc's guns dont single-ping kill, and they are not ju-88 dart guns either.. they require a decent burst of lead to kill a fighter. I could dive, do high angle attacks, etc... the concentrated firepower was amazing. I ended up diving home with a LOT of my plane in the red and only one engine (P38) left. I believe I managed to hit a Lanc and get one of his engines to leak, but that was it. THAT was a great example of how I think buffs should fly.
