How do you know I dont, you really are becoming insufferable you know, you make assumptions about someone based on no evidence, everyone who has had good games at some point gets accused of cheating, thats not the same as saying where someone really believes cheating has taken place <Lag Swiching Trophy Glitching etc> that its down to them being outplayed.
I had these kind of arguments years ago about the modding in MW2 on the XBL forums and some guys would say its you, you are being outplayed, I have never seen it yada yada yada, then the world went insane and it was everywhere so even these guys could not miss it lol.
They just vanished off the threads until the next game came out and off they went again its not the game its you yada yada rinse and repeat.
I noticed some matches yesterday that were just upsetting for myself ,kills that I should have had. I actually ran into a guy head on we met at a corner, I have dexterity on and released all 4 rounds of my M1216 into his chest. He did not have dexterity, however instakilled me with his SMG, I watched the Kill Cam, I never fired a single fricken shot and he unloaded half a clip into me. It happened several times yesterday that I was noticing instadeaths and shotless kill cams that were driving me batty for a minute. Our team still won, but I can only imagine how awesome it would have been had my streak not been ended by lag.
