It simply focuses on CDR (which is amazing on Ez due to his Q passive) and utility. It doesn't provide heavy damage in a short period of time. However, blue Ez can constantly stay at the max range of his Q and NEVER EVEN GET TOUCHED by enemy bruisers if you play him right. His damage potential is extremely high over the course of a fight, because the little bugger absolutely refuses to die.
