Yeah, I wanted her to have high mobility that can be used offensively but not defensively. I'm thinking that it wouldn't actually tell you beforehand whether or not the area was warded, so that if you try to use it and it's warded you suddenly have a long cooldown. Thing is, if you're stealthed, sight wards don't matter and it gets the reduced cooldown, and if there's a pink ward, you can see it anyway. It won't actually display whether or not you are currently visible.

Also, for the record, Kha'Zix's passive does the same thing.
