This build is what you need if you want to own at the first minutes and at the late game,what you need is Ability power runes and Spell penetration runes so you can use you first skills with success.At the late game what you will need is Attack damage and some Ability power,when your skills are on cooldown,you will be able to kick their *** with Attack Hits.Try it.Dont worry about your defence farm with your third skill ENRAGE ang gain some health,after that,GUARDIAN ANGEL will be perfect for your defence.

I personaly use only Ablity Power and Spell Penetratrion Runes because i believe that the whole game depends from the beggining,if you get 1-2-3 kills in the early game then the late game wont be hard.If you dissagree then you can add some attack damage and armor penetration runes. -->

If you enemy team has more then 2 Attack Damage champions you should buy Ninja Tabi boots.
