Thats what I did with americas army a while back. I played the game for the first time and after a few weeks I was still getting shot from people who werent even visible to me because of fog, or got grenades in the ass from some guy who stood at the other end of the map. I downloaded a hack to see if I was really that bad or if people would cheat that much... and I was shocked at how many people cheated... at least 50% of them... that was the saddest moment ive ever experienced in an computer game. I quit that game soon after.
I have given up on waiting for BIS to come back to their senses and do a real ArmA 2 successor.
