For whatever its worth, here's my take...
Last tour, I spent a lot of time trolling for bombers and developing tactics. I've also spent some time flying bombers in tours past. A couple of observations/opinions:
1) We shouldn't be able to run full military for so long, but I doubt this will ever get changed. So, I'll accept the hokie engine use...at least we can use it in the fighters as well.
2) The robot guns on the bombers--my biggest gripe is that if my rear turret gets taken out, I can still fire the other guns from the position. While my tail gun isn't putting rounds downrange, I can still take advantage of its incredible field of view and fire to activate the guns in the other positions, while using the sight of the tail gun. I shouldn't be able to do that. That screen should be all bloody or the sights immovable in my opinion. You shouldn't be able to fire the top turret from the tail sight in other words...
3) The formations--well, I go 50/50 on that issue. In one way, I believe that they discourage team-play on the bomber pilot side, while increasing the need for teamwork by the interceptors. Maybe a form shouldn't be perked, but the ENY lowered, as someone who successfully shoots down an entire form of 3 with all those guns should get more perks for staring down all those guns. Bombers represented an incredible investment in resources, money, and especially manpower. There's 30 aircrew in a form of B-17's. That's a lot of casualties for the loss of 3 planes. A B-17 in 1943 cost approx. $240,000 roughly equivalent to $2.7 million today. If I'm flying a P-47N and shoot down 3 B-17's, I land roughly 4-5 perks for killing 30 guys, and blowing through $8.1 million dollars worth of gear. I'm not sure that's equitable...
4) Bombers were the offensive air weapon in the war, and are in the MA as well. I think the destructiveness of the bombers is a bit unbalanced, as a whole. In the war, a successful mission equated to 30% of ordnance on within the target "area"--and that's with the then uber Norden bombsite, and missions that included hundreds of bombers. In the MA, 100% of ordnance on target is extremely easy. And, I won't even touch the issue of level bombing CV's.
5) Almost everyone had much more advanced warning of impending bomber raids which allowed interceptors to be positioned to defend against them. If we had radar that showed incoming bombers 3 or 4 sectors away (or whatever is a more accurate war-era range) it would make the whole issue much less frustrating.
6) Flak was the number one killer of bombers in WWII, and nothing over a base or strat matches the type of flak that you see in pictures of the big bomber raids in ETO. Only the CV can throw up that kind of lead, which strangely enough, seems ineffective against those level bombers at 6-8K.
Its a multi-faceted issue that I happily pay HTC $15 a month to figure out for me...
