Not trying to insult anyone personally but.....Holy CRAP!!!!! I am glad that you guys are not game designers...this game would end up so freaking complex that no one would want to play it. Guns jam? Bullets 0? What the??????
Personally I say remove killshooter and if you shoot down a friendly then you have to go to trial and risk getting courtmartialed and your wings permanently taken away. It will be a trial by jury, made up of the guy you shot down's family. Of course if convicted you will be banned from the game but still have to pay your monthly fee plus child support to the fatherless children of the guy you shot.

of course if you are found not guilty and that it was the other guy's fault for getting in your way then his widow will have to pay you a $10million dollar fine for the dummy getting in your way and messing up your shot, and his children will have to wax your car every month for 10 years.
SERIOUSLY
Current killshooter works because it is simple...you shoot a friendly, you take the damage. You might take minor damage or you might die. That's what bullets do, deal with the risk.
If you are getting killed alot from killshooter and its bothering you then you need to change the way you approach a target and consider everyone around you.
If you are just a crappy shot (like me) then do what I do, don't shoot until you are about 200yds or less and you are sure you have a shot.
If you keep dying while trying to save a teammate with a bogey on his six, then you need to practice your aim or change your approach.
If people keep diving in front of you just as you are about to take the shot then you need to quit swarming targets, even if you were the first guy in persuit and the other dweebs are tying to milk the kill now that you have the enemy on the run, sometimes its better to pull out and not risk a killshooter death, rather than insisting that its your target and sticking to him when there are several other friendlies chasing too.
