I agree completely with learning SA and making it part of your individual doctrine. There's going to be inevitable frustration for a variety of reasons...Ho-ing, vulching, or just doing something stupid. We never find out who our opponents are until you've killed him or he kills you, so you never know who you're up against.
I shot down a noob last night, he was flying southbound, away from his base, into empty ocean. Since it was the end of the night, I tailed him to see how long this would go on. We flew for almost 15 minutes, he'd make gradual turns, rolls, etc. I was never less than 1K away, so it was obvious I was there...we weren't even flying all-out...cruising along...
I almost felt bad for shooting him down, but I did, from 250 meters, straight on his 6. He never looked back, not once. Imagine how that person felt. Maybe he shrugged it off, maybe he called me bad names and wished me ill-will. Maybe he got mad at himself for not checking his six. I'll never know.
I've gotten really ticked off in-game. Not necessarily at another player, but at myself for allowing myself to get cornered, wasting E, or doing something stupid. I've also gotten ticked off at the game. I've flown for years, logged more than 3000 hours of flight time in all sorts of aircraft. I can fly the real-deal with no problems at all, but I SUCK in AH. I never flew AW, but did fly CFS and CFS2 online and was very competitive in those arenas.
There are so many variables that make someone a good, all-around combat pilot. With a game like this, everything from your processor and video card, stick, and keyboard mapping can make a difference. Add to that personalities, aggression or lack thereof, an understanding of ACM and SA (and practicing it!), and a knowledge of the aircraft you're flying, make this mess anything but understandable.
I know, at this point, that chances are I'm going to end up as someone's kill. Once in awhile, I get lucky and run into someone with equal or inferior skills and I land a few myself. I think by virtue of being there and participating, that you can improve by learning from your mistakes. Eventually, you run into someone with superior skills who makes a mistake and you get lucky and land a kill.
To many players, the 'big thing' is to land as many kills as you can before you get shot down. Personally, I'm happy just making it home. I doubt anyone will ever see me landing 3, 4, 5, kills in anything but a GV, but as long as I know I'm improving, I'll continue to play the game.
