unless you have force absorb on, if you get pulled from close by you ALWAYS fall to the ground. so what you have to do is, roll towards them, and hit the pull button, look where they are lying, and do a backsweep move. Offource there is the backwards walking saberspamming ppl.. those are just pathetic.. grab a gun to finish em off
if you don't have a gun walk around them while doing a red swing.. NEVER attack them from behind unless you've mastered the jumpkick.
As for defence from it, absorb, don't get to close, move fast, don't walk straight lines because your opponent needs to have their crosshair on you to do this right
