A while ago, I was playing jedi assault on Bespin with a friend and we saw Boba Fett, but he was rolling the same way he does in the air when he gets blown up but he was staying in one place: where one of the slopes meets the ground. My friend struck his spinning body and it traveled along the line where the slope meets the flat ground, still rolling. We hit him back and forth until someone lightning'd us.
That's...interesting. I've seen it done on stuff like the end of the giant barge on Tatooine assault, but not on the ground.
Reminds me of a Pull Tornado (Being caught between two people constantly using Force Pull). Too bad you didn't get any pictures of it!
