The helicopters need to be toned down. Right now, in the hand of a competent pilot, they are basically invincible with unlimited ammo. Even after 4 direct hits from the Stinger, they are able to stay alive because they can be repaired so fast. Make it with limited fuel, limited ammo and reduce the repair speed so as to avoid the killing fields we are seeing right now with guys getting 50+ kills in a round where other top players get at most 15 to 25 kills
