I bomb a lot, and I do agree with some of this. 4-engine bombers are not dive bombers, and their bombs should NOT release unless the autopilot is in level flight and the player is in the bombardier position. Period. The driving of lancstukas from the pilots position in F3 mode and carpetbombing the gvs is just playstation gamey. That said, there are plenty of twin engine bombers (JU88s, A20s, B25s, B26s, etc) that did dive bombing and attack missions, and these should be gone thru on a case by case basis to see who should be allowed to bomb from the pilots seat. (Somebody check me, but I don't think the Betty or the Ki-67 did dive bombing).
That said, the gunnery is just fine as it is. You have told them what I DO get - let me tell you what I DO NOT get:
1. I don't get 8 sets of eyes searching the skies for enemy fighters.
2. I don't get gunners in multiple planes engaging multiple targets at once.
3. I don't get the ability to have my gunners actually engage anything while I am in the bombsite over the target.
So if you are insane enough to try to crawl up by B-17s tail, I can step on the rudder and turn right & left, but I am not pulling some high-G split-S on you. I may go ahead and nose up or down to make you have to climb up to catch me, or give you a longer tail chase, but that is about it.
The "bomb and bail" problem is not limited to bombers - I see plenty of P-51 base porkers that do the same thing. A quick suicidal bomb run, strafe a couple of strats until the ack gets you, then rinse & repeat. The disappearing bombs solution you propose would do nothing to stop either one, as I could just wait until bomb impact then then fly into the dirt and crash instead of bailing out. A lot of coding by HTC for no benefit at all. The problem is that there is very little benefit to me flying home (in either a bomber or a fighter) unless I need perks, and I usually don't. If there was some other benefit to actually bringing a ride home that might change (and there have been some other proposals in the forums about that).
