-The first person to get hits on the plane regardless of damage gets the kill.
Nope. Even as it is now, I'll sometimes get the first hits on someone, then let them go, knowing that when someone else finishes them off later I'll get the kill. Sure, once in a while I only get the assist but more often than not I get the kill with almost none of the work but I do enough damage to assure myself the reward.
Why let skilless people claim the kills when they obviously aren't adept enough to cause the most damage?
You'de get people B'n'Zing through a furball hoping for one lucky ping on as many ac as possible. Does that qualify them to be rewarded for the kill? I think not.
