I found the coolest trick for duels and WSG (also for getting around fast)
all u need is to be a rogue and have Sprint on or have sprint and stealth
if u look on ur modem ull see a button that says "standby" if u use stealth and sprint at the same time u can do this well and avoid like 10 mobs. if u use then press stand byit freeses the game and all other players keep waling in wierd directions sometimes into walls but dont go through.
by doing this u can pwn in WSG and duels or get past that lvl 70 that keeps kiling you so bas u feel the pain that ur player usuually takes.
dont flame
this is from the robotrage trick and halo2 trick
if u know a program like fraps that records vide on a mac tell me!!!!!! i will make a video and post it in an edit!!!
hope this helps, Varthorn
