I played 16 hours worth of matches during the last beta. I never once ran into anybody I suspected was cheating. Granted, that means I didn’t play against everyone but I played at all hours and for many hours so I was exposed to quite a few. Also, I am an ex-CAL Anti-Cheat admin (showed my age there) and worked with Punkbuster quite a bit so I do know what I am looking for and I also know enough to not suspect good players of cheating right away.
A lot of ex-wolf players are playing this (myself included) among others so there will be a few highly skilled players as this game translates well and they will be packed in with new player who don’t know what they are doing that help balloon their scores which encourages thoughts of, “that guy must be cheating”.
So I am not discounting that there could be cheats already but I have yet to see anybody that seemed suspicious and cheats like wall hacks don’t work very well in this game due to the pace and some class abilities anyway.
