Cheaters, cheaters, cheaters and more cheaters. Free game = loads of cheaters.
So it comes down to the fact that even if you play well, everyone calls you a cheater, hacker, loser and whatnot and now they can kick you out for it too. This game is now beyond help, everything stinks of cheating and the game should be put down like a dog that bit its master.
So if you want to play a game where people take pride in a well executed plan, skills, sportsmanship, forget Combat Arms. It'll never happen in this game.
Unfortunately everything that has "free" on it attracts the retards of the planet.
