i think it´s way too easy.yesterday i downed approx. 10-15 choppers per game with my sniper rifle - an very relaxed too.
they were trying to hit me but with those awkward heli controls they had no chance. one was even landing right in front of me and stepped out to finish me off by hand, but >boink>
altogether, i think the flying vehicles patch is not that hot altogether and i am actually back to playing the "old maps" -more fun, tactics & thrill.
P.S.: btw, the choppers are also way too loud, u can spot a heli-rush from miles away!
