Bet you get just as angry when you light someone up first pass nose to tail and they fly off unscathed, just to get an assist message later. Bet you don't complain here in the forums or in the game when you are surprised you get the kill message on someone who obviously is shot up.
The "vital part", I thought it was a count down counter except where the pilot's head was concerned. In effect, you are asking the person who hit the plane with the last single BB as it was falling past him, to be awarded the kill for being lucky. Wouldn't that Pyu you off even more?
Some of the 50cal people are angry about the first circumstance I mentioned. In that case, you are asking HiTech to give away most of their kills to others no matter what they do. Leaves the door open for a new breed of tardling bottom feeders. They will watch and wait for you to wound someone, then blow through to put that last BB in place to pad their kills message and never have to fight for anything. Clearing someone's 12 and running will become a dirtier word than HO. Especially since killshooter works so well.
At least what you are asking for will have players PMing the correct back picking, mud sucking, mother whacking, SOB with naughty love messages. Your kill didn't give your con the message that you killed him. It was that other useless tardling in a P39, P40, P47 or P51 who lit him up nose to tail with a perfect deflection shot after some white knuckle ACM and he ran away with apparently no damage from the perspective of to the original shooter. Who unlike you, didn't run in here to record a large whine to HiTech about how unfair the game is and he needs to change it.
