yeah i agree the guys in the choppers are just very very skilled, i wonder if you have been pwned by my good m8 oner1r, although he's not just a chopper whore hes an all round very good player.
Oh and i think your on about the quick scopers (QS) that are getting you with the bolt action sniper rifles and bunny hopping.
BTW there is a sniper rifle that is VERY effective against the chopper
and no im not going to tell you.
