I think he is more of an assasin/jungler/solo top, similar to Lee Sin because he deals alot of damage early on, and falls of (damage wise) late game, yet he can provide some uttility to his allies

He has some makeshift escape mechanisms (mostly his E), but he can gank others very well.

Therefor I belive he should build:

damage items such has: The Bloodthirster, Infinity edge,Trinity Force, Maw of Malmortious, etc

defense items Warmog's Armor, Mercurry Threads, Ninja Tabi, Atma's Impailer,etc
