Vault can't miss. Although, Vault can't be used as a gapcloser unless there's an enemy minion or someone else behind you, and it can't go through walls unless someone's got you against one and they're close by. Maybe a Vayne condems you into a wall, you can vault to her and leap over the wall. I think I favor 90 C.N over Vault, since it can be used anytime and requires less of a scenario to play out how you want it too.
