"and there is no Grand Prize for most kills "
Perks.
And it is a REAL low thing to do, to see a con burning and spiraling down and see some moron come along and shoot it to do "more damage" than you did and get the kill (and perks).
Few nights ago some dickhead killstole the F4U4 I had smacked both wings off in a lucky snapshot. He tumbled down , clearly visible that he was dead from the d4.0 I was seeing him fall from.. and this spitdweeb comes along, dives after it and blasts it into a fireball...and gets the kill and I an assist. Times like those I wish there was no killshooter.
