Another problem, which I'm surprised you guys didn't mention, is that the bullet streams from one bomber passes through other bombers without inflicting damage. There's no "interrupter gear" in work for drone buffs, like the one we have applies to the vertical stab.
As a result, the historically more probable method of buff hunting doesn't work. Technically, the outer most buff should be the most vulnerable. In a 3-plane formation like we have, hitting the left or right drones in respective directions should be able to negate the fire from the other two buffs - except it doesn't.
In short, where ever you are, as long as the gun position has a firing angle, you will ALWAYS face multiple guns from all three bombers.
