I'd much rather see killshooter off, friendly planes damagable, and PNG status after the second friendly kill. Since *both* pilots are at fault in a friendly fire incident, *both* pilots would be affected in a negative way (one gets shot, the other could lose his right to ammo).
Second to that, what we have now is ok, but it only punishes one person, when two are really at fault.
If friendly fire did nothing, it would be rewarding 'kill stealing' (whatever that means), 'gangbanging', and all sorts of other dweeby behavior.
Contrary to popular belief, it doesn't take 5 planes to kill one Geroge on the deck.
