OP:
No. The current system in place is better than what you have described. We had something like that in the past and it didn't work well, with people "kill stealing" (I've had it happen more than a few times). Have better aim (for the record, I couldn't hit the ground with my hat in 3 tries), or choose a plane with a bigger punch.

Ganging to the 10th power.
Conversely, shouldn't the guy who gets shot by all those hand holders get perks instead? You want to give perks for tag teaming, but what about the guy who has to fight the gang? Certainly more perk worthy than what you propose.
Being rewarded for inflicting damage isn't an overly bad idea. It is how they go about implementing it that is the doozy. But think for a moment, if HTC were to implement it, I would HIGHLY DOUBT that it would be in a manner that would result in this. The reward would be just enough that a player gets something for their hits, but not enough to "farm" it. Personally, I don't care.

Getting in there and shooting up stuff is fun, whether I get the kill or not.
