Who's playing the game? I'm seriously having a blast as a assassin.
It's actually the only class I'm able to play effective to get 20+ kills without getting killed 34223 times.
I always play as Tank and own nubs if your not dieing a lot as an assassin then you are facing piss poor tanks or just tons of nubs, havent been on in a while though mostly been playing world of tanks to get as far as i can before wipe so i can rage quit after to break my addiction to it.
I play all classes and still get pretty good scores. I won't claim I own certain classes or people, cuz the game is mostly about teamwork and not your solo effort.
Though, I did get my 1st MVP achievement using a Sniper.
