Your item progression is horrible (you want an item or two before you shoot the moon on getting the IE). Your Masteries are messed up (master yi doesn't use AP and his ult insta cooldowns so dont use ability cooldown masteries). No rune set at all. Finally your ability progression is completely messed up (you should be getting all of wuju style before you take more than one point of alpha strike). All and all you are getting there but you have a ways to go on revision.

This Equip is good, but your masterys sucks.
