Its no worse than a guy who sprays a flight of buffs with all his ammo to no effect, just a lot of hit sprites that don't do any damage, then ends up gliding deadstick and missing parts, but they guy who lights it on fire or kills the pilot with a well-aimed precision burst and doesn't even take a hit only gets an assist.
Just the way the scoring system works sometimes.
Notice the guy who gets the kill for nothing is never the one to complain though...
