So 2 extra planes, 3 times the ord, and 3 times the defensive armament isn't an advantage?
The K/D is deceiving, because of the many folks who will, as an example you're extremely familiar with, drive formation after formation after formation of buffs NOE into the side of a CV, or, as another example, the guys like Fortress who would do the same thing trying to take out hangars. Waffle used to up formations at a capped field to lure the vulchers into wasting ammo. The BKs used to up formations en masse at a vulched field, figuring they can't get everyone. And, as you know, once the drones are airborn and the lead plane is killed, you're instantly in the air and gunning. I should also add the people like me, who will fly to TT, bomb the neatly aligned rows of spawncampers, then troll for fighters until I'm out of ammo or drones, something that simply wasn't possible before drones were added. Bombers have created a lot of wildly unrealistic situations in AH, and I (and others) don't think they've done anything to improve the game.
And of course, the main point in all of this is that formations were added so carpet bombing in single planes wouldn't be an exercise in futility. But, we don't have carpet bombing, we have nearly the same accuracy we had in AH1 (this might be before your time, not sure), except we're dropping 3 times the ord.
