When a B-17 strayed away from its bomber formation, it was in SERIOUS trouble when one or 2 fighters attacked it.
This was in RL, with a plane that had human gunners on EACH gun.
Yet here we see a Buff laughing off attacking fighters because all the possible guns are aimed at the exact same point where the human gunner is aiming. So the 2 .50's of a tail gun magically become 4 . 50's if the attacking fighter is a bit above the exact 6 of the buff (or below it), and god forbid, if the bomber TURNS and tilts to one side you are suddenly faced with incoming fire of EIGHT .50's all aimed at the exact same spot as the human gunner's 2 .50's are hitting. Momma! Talk about convergence!
Not to mention that when you manage to be on the perfect 6 cloc position and get a GOOD burst of 4 .50's and one 20 mm cannon into the tail of the buff, you dont knock out the tail gun! I can believe that the gun itself isnt damaged, but the gunner? He should become a splat on the rear of that buff.
All these things have made me sick just to think on attacking a buff. So I dont even try any more to set up an attack or what not. I will just go in guns blazing and hope to blow it up, rip a wing or RAM it once the single-mega-ping of death makes my plane spin. If the whole point is to stop the buff from bombing, I have no problem to just go in and ram it out of the sky.
I climbed in 5 minutes, he has been climbing for an hour. Would I be annoyed if I was a buff? hell yeah. But then again, the LW did create squadrons of Fw190's whose sole mission was to ram the tail stabilizers out of the b-17s.
So far, this is the only solution I can think of for this problem. Tactics, high speed attacks are all fine and dandy, but they dont work when ONE lucky ping from the gunner means you got hit by more than the 2 .50's the human gunner should be firing at you is just plain ridiculous imho.
And to those that say that a fighter should not solo a buff I say: Why should a buff solo a bunch of fighters? I mean, Cmon! If we are forced to gang up on a buff just to be able to kill it, just to have a CHANCE of killing it and living to tell about it; why shouldnt buffs also be forced to fly in numbers so that they also have a chance of doing their job and surviving? Hey wait a minute.. thats how it really was!

Rooks and Bish have done WONDERFUL formations of buffs. I would think twice before attacking a formation of 3 B-17's even if I had my wingman with me and had an alt advantage.
