if you want to learn how to spar you should consider these facts of differences:
the sparring mod has heavy gravity(-30.00) compared to lenshu, also sparring starts you off at a greater distance to your opponent, which is why its vital to learn how to run(

remember running only works on a gravity of -30.00
sparring also has to have a bit of realistic flow to it, like doing a flip and landing on your feet, not your hands.
and doing punch's, kick and stuff, not simple stupid things like noob clapping.
sparring also has no dismemberment, fracture, or dq.
its sorta like charging at someone and beating the cr** out of each other in a realistic way...
