Hmm, well, I would like rolling to push people a little. That would be nice for when gankers are completely blocking you in.
And dead enemies should immediately lose their physical pushbox. Too many times you kill something to clear a path and their dying animation takes so long that you die before you can escape through their soon to be limp bodies.
