I hate this. It makes sense in certain circumstances when the target has escaped an engagement and the kill shot is a separate action, but when its a tank dead in the water actively getting shot by me after ive bombed it to a burning heap, dont give the kill to the late larry.
And yes i care about some stupid 380 points so i can get a slightly higher k/d. This is all i can care about when we've lost the game for no good reason.
