Thing is people will always complain when they find a new tactic they cant beat. its human nature. way back when multiplayer shooting games first came out there was uproar over sniper rifles. 'Thats not fair, he can shoot me before i can shoot him.' Games change, learn how to beat these new tactics and you may get the kill you wanted. you can always complain that something ruins a game just because you dont like it or cant cope with it, or you can learn to beat AAs.
