I wasn't saying invisibility junglers were common, just saying that it serves exactly the same purpose as gap closing abilities... at least as far as ganks are concerned. And Kha'Zix's Void Assault lasts a minute, and can be cast twice before cooldown. IMO it's best used when coming out of the brush, because typically you won't appear until you're right on top of them.
