BUG: Camille can q out of stuns, roots, grabs, and WW ult

Her E is the one that makes her lock on a wall, not her Q.

not a blink like Ezreal.

That's because it's a self pull. It will drag her if she lands on a structure. Plus she can only do it if the ability was already cast. Once those hooks are out you have to stop her mid flight. Just think of it like Trist W.
