Country gang banging happens. Every side whines it happens to them the most, when in reality it happens to every team at various times. Even the different maps tend to produce different "gang bang" scenarios. Bottom line is that overall every team gets gang banged at some point or other.
Inserting artificial methods (i.e. AI) in an attempt to overcome this is, IMHO, the wrong thing to do. Sure, we all get upset when the other two teams are beating ours mercilessly because most everyone here is very passionate about this game. Obviously you are because, even through all the griping and moaning, you fediddleers are logged on here every day beating the crap outta each other

If we want to eliminate, or at least decrease country banging, then think of ways to do it via player methods. Personally, I think a fourth team in the game would go a long way to that end simply by default of the map locations. If 2 countries immediately start off banging one team, the 4th team, due to location, has no choice but to hit one of the 2 teams participating in the banging. Like it or not, quantity USUALLY overcomes quality in this game. He who has the most players on usually wins. Of course, we see big sawys in that depending on time of day as numbers fluctuate, but the end result is usually heavily dependent on numbers per team.
One other thing that I think might be interesting would be to borrow a game play strategy as was used in Warbirds. The rolling plane set. Start a tour with only certain models of aircraft or vehicles available based on a time frame. Sure it's been used before, but has it been used in AH? I think what a lot of us are really wanting/needing here and what we really haven't keyed on, is a change in overall game play variety. Maybe HT could implement various types of game play spread out over time periods. Rolling plane sets set on a 2 week time frame, followed by a "non-perk night" (i..e. ALL planes are free). Or at least something along those lines. Something to break the monotony as it is and force us to reinvent tactics and or play by different methods.
