I've seen some newer people in the game with some pretty solid skills this weekend, but I haven't seen anything much that I would consider highly suspicious. I see tons of accusations flying around and, to be honest, there's nothing to most of them. Usually it's people who just can't deal with how much better than them some of the people that play this game are.
As for banning groups, I think overall it would be bad for the game to prevent people from playing with their friends and clanmates. The social side of the game will be very important to its success.
No one who is new to a game should go in expecting to not take a beating at first. All of us who play the game have been through that, learned to deal with it and became better at the game as a result. Many of us joined groups of our own.
My advice to anyone that's new is to just play and learn the game. Accept that you're going to lose a few. Find some cool people to hang out with and don't worry too much about it. It's just a game, after all.
i agree with you some people accused me of cheating just cuz i got 30 kills in one of my games with a low rank
