Blue Ezreal is Ashe with mobility...
Seriously. Once he gets that IBG it is like facing an Ashe who has movement speed and flash up every half second. And yes, Ashe gets her slow from Level 1, it is also crap till she gets some items and levels. She also does not get riftwalk and has a 325 movement speed...
