I have noticed the same MA change in behavior of late. It seemes to be squad dominated. The replies about getting organized or shut up, or similar, would actually seem reasonable but I will make a case for the original poster's point.
As a game, it is only going to be successful if everyone playing has fun. If folks aren't having fun, they'll give it up. Getting organized is a great strategy to improve scores and achieve objectives but it frustrates the unorganized. That is important when you realize that the all of the customer base can't be as organized as some. Organizing yourself into a squad and learning to fly with them, takes a bigger time commitment than learning to fly your plane and hopping into the action. Many can't put in that kind of time. I also disagree that this organized behavior is for those without skill. I think it's just the opposite. I've spent many an hour getting my butt handed to me by the AKs, the muppets, The Few, etc. Hardly skilless lemmings.
Flew for 2 hours yesterday morning in LW orange with 275 people in the arena and got 1 kill. Single planes ran. People only engaged if they had 2 or three squaddies with them. Logged on later and the only action was furball with about ten unorganized individuals fighting a squad of Me-163s. After an hour of running, and dodging, and watching "joe-blow as landed 6 kills in a Me-163" messages, I just logged.
AH is becoming a team sport. Soon only the teams will be left.
That may be fine, and I don't think rules changes should be employed to "correct" it. But I think the game is more fun when the MA is statistically random in it's activity, pilot skill, game play. The team order that is evolving is eliminating the randomness, and what results is large areas of inactivity, or large areas to overwhelming odds.
That kind of play, if consistant, will drive away single players.
The only real solution is for the squads to exersise a little restraint. You don't need to be told what an unfair, un-fun fight is. Just avoid doing it. After all, you are organized enough to control the action. The choice is yours.
