Ive said many times on these forums that there is a very large section of raiders who bot... but nobody beleived me. The Fanboys think its just a bunch of hackers in China who bot but ive known dozens (maybe up to 100) of players who set up botting software on their accounts.
This doesnt surprise me whatsoever and i still believe that the botting issue are far more common among longtime players that Blizzard will ever admit.
