Must be a internet thing because I don't understand that. You mean to tell me a computer cant compute that if I got rammed the other guy wasn't in the collision? Sounds like cyber BS to me. 
So what your saying is you dive through a furball, and some hoser NIK turns into you for the big HO maneuver, you see this and being the better cartoon pilot kick rudder and do a tight barrel roll and watch that HOin NIK pass right over your canopy and.... BANG, your in the tower because he collided with you on his computer. Oh ya, that would work out sooooo much better. Due to that quarter second lag between your two computers he didn't see your awesome move and so collided. Are ya sure you'd like it better that way?
Until the internet connection becomes "faster than light" fast, what we have is about the best your going to get.
Half of your suggestions had to do with points. I think the "bad game play" is DUE TO POINTS ! Everyone is all out after points so they do what ever it takes. That means divebombing lancs, stukas dropping 1 big old bomb on strat then bailing, HOin as many planes as you can get before you get shot down, spawn camp as many GVs as you can before the camp gets busted and so on. You want to play with points???? how about 25 points to take a base.... divided amongst the players in the mission. 5 guys take a base = 5 points each, a horde of 50 = half a point each. If people want the points they will figure out how to plan missions with less guys, or split their hordes into a couple of strike forces to earn more points.
Kills, 5 points per kill, 2 1/2 if you ditch, 1 if you die. Doesn't matter what your flying, or driving. You put enough rounds into a target you get the kill. No more proxies, you crash, you die, you up a new toy thats it, no points, no name in lights for the other guy who just happens to be close enough to laugh at your "technique".
If you have to have ranks, base it ONLY on the points, not hit percentages, not k/d, not things that can be tweaked. Sure this will make it lopsided toward those that have no life other than AH. Award the ranks on a curve as compared with time in game.
This game was a blast EVERY night when most of the people only cared about the fight. Fights in GVs, 1 vs 1 in fighters, even the fight for territory was big, but that is what is was all about, the fight. Thats why you logged in, it was to fight, not to "build your points in a buff tonight because Im slipping back", no body cared. Lets get back to fighting, which ever fight you like, do it. I would love to see the score page get shut down for a month....... how much to get Skuzzy to trip over that wire?
