Somethings confused me in Battlefront 2:

1) Since when could the Emperor float-run? I've never seen him float before, and how can he roll when floating? It might be the Force but it just sounds weird.

2) Why do Palps and Vader float in the air for a short time when they force jump? This also allows them to force jump further than most Jedi/Sith.

3) How can Vader boost (for force speed, he zooms to a place faster than your usual Jedi/Sith character) (Palps can do it too) and jump (and float-jump)? His legs are mechanical, but not like GG's legs and he's a not-fat guy that is heavier than a fat guy. Shouldn't the weight make him fall faster than it does Palps (maybe it is the cape), and the boosting, wouldn't the weight make that impossible also?

Comments and answers are welcome.
