Honestly, its a bit hard, at least for me, you need to be extra careful, the sniper oscilates more, to sum up you really have lots of factors to consider before making you move.
In games like C.S and Crossfire and AvA and similar, you can be a Badass Rambo!
But here you need to have proper communication with the team, and need to think more before acting, or you end up dying.
Thats what happened to me, team full of noobs, incuding me, well, you get the outcome.
Nevertheless, the game is pretty good.
