I doubt his pushing... is really that good. He has to autoattack a lot. which'll leave him quite vulnerable unless he has access to Infinite Duress. before that, you'd be very suspectible to constant harrass which you'll most likely be unable to fully recover from before the next onslaught, this problem is... further increased due to his low mana pool.

Well, that's pretty much one of his biggest flaws.

other than that his mid lane is quite solid.
