Yeah I never understood why they mix asian and western player populations together like that. There is obvious cultural differences, of course there is cheaters of all creeds, but I promptly stopped playing this game when the chinese flooded it. No fun in playing a team game whera A. You can't communicate with your teammembers, B. Your teammates will shoot you in the face the moment you get better stuff than they have. (Had chinese do this to me 4-6 times in one day).
Edit: removed inappropriate generalization.
