I must be doing something wrong...I abuse sounds and hear people coming because of it, and catch attack patterns and catch people off guard left and right and am constantly up on the leader board...but I've only ever been accused of hacking once or twice =( lol
Lah Jobo and occasionally Starraven are pretty mean snipers..people not used to seeing good ones might think that but if you watch 'em there's nothing wrong with 'em ;p
