Wow. Kong used two whole sentences... almost
I understand your POV on this Tex. I do think the AvA arena balances out the gameplay. Hording, vulching, camping, either way, it's poor gameplay, but it's definately not the norm.
When I see a 1v1 battle going on, I always Always ask - do you need help? If the player does (usually they ask even before I can say something), I give a hand. To the opponent - he has to be watching his DAR AT the same time he's dogfighting. I do. Situational awareness. It's similar to WWII and pilots asking for sit-reps to a local air controller.
Dar keeps us alive. Ignore it, it'll kill you. I.e. you're dog fighting a lone 109 in your Spitfire, gaining advantage and his two squad-mates show up. As a squaddie, I would EXPECT them to help. As the Allied pilot, I SHOULD, every once in a while take a quick peek at DAR. It would be equivalent of listening to the forward air controller announcing contact reports over the radio. Tune out the contacts, or in our case, RADAR on your map, consider yourself flying with blinders on. And we all know what happens when you get target fixation.
Another point, squads in any area are like the modern gangs, but more structured. You always help out a brother in need, so when it appears like it's a 3 or 4 on 1, chances are you're still fighting the same guy, but his pals are bothering you so he can line up the kill. As a former JG54 pilot, it was a classic act. Beat up the opponent, let the guy who deserves the kill close in but keep your enemy boxed in.
Also, engagment tactics are what they are. Many, and I mean even the best pilots in WWII used a HO shot or snapshot at an initial merge to wound their opponent or force them into a counter-move to take advantage of positioning. An opponent caught by a HO shot wounded makes a much easier kill. You just gotta be careful enough not to be caught by that manouver.
And you're right - people are not out there to actively destroy our fun. This IS a game after all, and a game is a recreational activity involving one or more players. In Aces High, it can get personal because we often befriend one another and get passionate about how we play...sometimes a little too much.
