Holy crap CQC sucks as a new player.

I came back to the game after who knows how long away, and man, it seriously sucks to play CQC as a new player, and I can only feel worse for my teammates. I do crap all to other players, I maneuver like a truck skating on ice. I'm sure a very large part of this is me just playing bad, but, wow, how in the world is someone who's new to the game supposed to have any idea what to do. Holy crap it sucked. Anyone have any suggestions on where to go on how to actually fight worth anything? If I actually could do anything CQC looks like it'd be far more fun then anything I tried in the persistent part of the game.
