First, formations weren't that "massive" in rl. They were about a max of 36 planes in a squadron, stacked. These "formations / squadrons" were spaced over hundreds of miles. The idea that 100s of planes flew in some sort of mutual suporting formation is nonsense.
Second, even with the bombers in these formations the accurracy of their defensive fire was low. The best strategy to project the bombers was to intercept the enemy fighters before they could attack, particularly while they were forming up.
You are right that they are still more accurate than in reality, but the fact is that is they get any weaker they will be absolutely useless and bombers will go away completely.
One can only hope, but in events in ToD where we see larger formations of bombers they have the added advantage of more accurate fire power. This usually gets offset by the lag in that the bomber gunners while in large formations and attacked by large groups of fighters have trouble tracking the attackers due to the warps that follow.
Most bomber formations in events when they get attcked are attacked until they are entirely destroyed. This is because of the suicide nature of the attacker and an improper undisciplined escort strategy..
However, in AH most bomber sorties consist of 3k noe suicide raids or the much talked about "4 eng dive bombers". I could argue that if the bomber defense guns were as accurate as rl then it would force folks to fly them in a more realistic fashion. But we both know that isn't true.
First, there's very little reason to fly bombers now. Large gaggles of fighter-bomber raids and much more efficient.
Second, despite all this call for "organization and team work" folks would just stop flying them all together as you suggest. Which wouldn't be a bad thing imo but woulkd alienate the 15 or so guys that are regular bomber types.
