1st No kill to death ratio.
Kdr doesn’t belong in battlefield.It was someaht important in bc2 because of the smaller scale of things but in most games it rarely matterd for anything and ruined the game because of the bush wookies.It shold have no point in bf2.If you go 20 to 2 kdr it barely mattters unless those are all vechile kills,but just killing random inf doesn’t swing the battle to you favour enough.

2nd Should vechiles cost tickets?This happens in pr I believe.It would prevent people from wasteing vechiles.Granted jeeps an little stuff wont cost anything.The down side os that some airplane/heli noob might crash alot and cost your team alot of tickets

3rd-Instead of a K/D use a "squad" K/D.Crazy,but it will promote teamwork.Maybe incoraprate idea 2 into it two.HAveing 3 men die to destroy an attack chopper is a worthy sacrfice and it would suck if the squad got penalized for it.
