A big ROFL Pyro, good one.
On the number of countries issue. I can't see that 2 countries or 4 countries would prevent imbalances anymore than 3 does. I kind of like the unusual situations that can be caused by fighters showing up from more than 2 sides. Once in a while you may see me up there participating in my favorite sport, BnZing a fight between the other two countries. Haven't figured out how to do it properly yet. Sure is fun though.
What would help with the imbalances is a bunch of players who were willing to switch to the smallest side when they logged on, or to switch any time the smallest country started taking a pounding. I would think the best pilots would like to do this because they would have more targets. This used to happen quite often in the early Beta days late at night when there weren't many people on.
On the subject of the ack and bomber accuracy, etc. Things are okay for now and there is no great hurry to change things if it means delaying the introduction of new aircraft, etc. That said, I am always in favor of historical accuracy, it makes me feel much more like I am doing something similar to what really happened and makes the game easier to relate to history. To the extent that things are not historically accurate I begin to feel like I'm just playing another designed game like XWing or something (definitely no slam of AH meant here, I love this game). It's always neat when situations develop in AH that are similar to what you have read about. And I would just love to see big puffs of black smoke appearing around my b17 as I gather my courage and fly straight and true so my bombadier can drop his payload on target

. I know there are some problems involving vulching and the number of bombers available, etc. but If these could be worked out I think it would add to everyone's experience to see realistic flak or to man a machine gun shooting down incoming fighters once in a while. Come to think of it what did they do when the fields were close to enemy fields? There must have been some sort of CAP up to protect fields.
If we had realistic ack, less accurate bombers, and perhaps bigger targets that still didn't require any more bombs than they do now, wouldn't these things all balance each other out and produce more realistic situations, such as bombers having to descend to drop their payloads and face fighter interception? I think it would also make bomber escorting much more of a high art and much more commonly practiced than it is now.
Keep up the great work HTC. I really curious to see how this game develops. Would be really neat if players could feel like they knew what the real thing was like. Hmm, wonder how we can set up the refrigerator peripheral to simulate high altitude
