Sadly not here anymore and while he did used to talk some rubbish on 200 it was mostly highly amusing! and unlike almost everyone else in this game he matched his words with his actions in a fight even if that meant he lost!

Silat is one of the nicest guys in the game and would help anyone out regardless of who they are, or how new they are.
Soulyess is another top guy funny as hell and fights with honor, still can't spell his name right!
p.s - I really cannot think of any other players I've run into recently that improve gameplay at this moment in time, there has been a marked decline in people who subscribe to the 'its about the fight' philosophy, and the game is poorer for it.
