well first thing NEVER USE AIM BOT OR SPEED HACK now i think u didn't use em now when uand some one fighting always keep jumping then siting so he can't catch u and u can regain stamina and when u SS/FB always aim on feet or shadow and try to gues when oponent jumps wr did he jump and ss at that place right before he lands and try not to fight any one when ur laggy
ah and btw remeber to jump alot and put hotkey of sit in F2 or wherever u want and sit to regain stamina
