[OK, bear with me here. I am trying to make a point, but not really trying to aggravate everyone. Just having fun with this.]
To boil all this down, I guess there are two basic kinds of flyers here as reflected by these responses on Check 6's. I'll call them the Indies (individual flyers) and Teamies (teamwork flyers). And not knocking either type initially, they just have different goals and experiences in mind in AH.
Indies want to shoot people downl. Now, right now! Lots of them. Anybody who gets in front of their guns is fair game, icon color not withstanding (fortunately AH prevents this cannibalism of attacking green). That's pretty much the point and enjoyment of the game for them, and any other consideration is obscene, undesirable and ignored for the most part. And I guess that's fine for them. It's their dime. But what they don't seem to get is they only win against individuals one at a time. Nothing else cause they really don't contribute much to anything else.
On the other hand, Teamies like to personnally kill their enemies too, but while shooting them down one-by-one is great, they thinks its way better to beat the crap out of ALL of them at the same time. Like maybe actually take a base away from them and piss them off. This is only done through teamwork.
In fact it takes only a small amout of teamwork usually to achieve this, AND Teamies do get to shoot down planes occaisonally. What a bonus!
And it's really great fun to screw-up some bad guy who's thinking he's about to make a kill with a simple Check 6 call. Or shouting a "turn him right, turn him right and he's dead!" call that sends him fluttering down in flames when he almost had a kill is priceless. And it happened because the Teamies, as best and as much as they can, protect each other.
And that surprised pilot? Well, he and his buddies were all Indies and thinking, "Watch your own 6 idiot. What were you thinking? That I'D help YOU!"
