The fact that it has no additional effect over the other ones you listed doesn't really make up for how good it is. A 60 mana 1300 range blink on a 6 second cooldown is INSANELY good. That's nearly as short-cooldown as Kassadin's ultimate, with infinitely better mana costs and has way better range.
