Massive FlaK batteries around GV spawns

.
+1, I can't tell you how many times I've had a good fight going, me and another tiger slugging it out at long range, and boom, I can hear an 'effing cookie dropped my way. Since the cookie gives the kill to the lanc pilot, I loose my perks, have a fun fight ruined, AND don't even get to know who I was fighting.
I'd say you loose 1/3rd of your perks when killed by a plane. It means theres less of a reward for bomb****s (often they do it to screw tankers out of their perks), it makes it harder for the "No fair, you're not allowed to shoot me

!" crowd to ruin a fight because they're upset, and it leaves the aircraft's ability to defend a base and uncamp a spawn perfectly intact.
