Yeah, I know the move, its great fun. Using it for an advantage could be considered cheap if others dont know how to do it, but as far as Im concerned its there for fun.
Have stormtrooper skydiving contests on Nar Shadda maps
Other cool moves/bugs:
roll catapault (use it on yavin temple to fly over the walls when you start at the sides)
Launching up ramps in Death Star (i think most people know this one since I saw it on the forums a hile ago, but I'm looking for other places to do it)
I'm not saying how to do them here because I want to see how many people ask how to do them. I need my feelings of power or my egoshrivels up and falls out of my ears.
