I'm not saying that the isn't cheating, but I just don't really see cheating happening very often at all. I see it maaaaaybe once in a blue moon, true cheating that is. I suspect that what you're referring to as "cheating" may actually be Bungie's "catch-up mechanics" in the game. Are you an average 1.2 k/d player (like myself) and in a match, at the beginning you're doing great, but then halfway through the match, it feels like all of a sudden your thumbs stopped working, all of your shots are body shots, and that 0.6 k/d player on the other team has suddenly become super accurate, and destroys you in every gunfight, all the way up until about 2:00 left in the match? Then in the next match, suddenly your the top guy and finish with an "undefeated medal", even though you're playing against the same players from the last match that kept destroying you? Well, my friend, what you're experiencing here, are the catch-up mechanics that are developed into the game, to make the matches "more exciting".
