User blog comment:YourPrivateNightmare/The mystery of Blue Ezreal/@comment-6906412-20130617014622

Ok so I've been over this before a lot with my friends, and here is my analysis: Blue Ezreal is a build designed around﻿ poke comps. Compared to other "standard" ADC builds, a "pure" Blue Ezreal suffers from no critical strike or lifesteal, reducing damage by about 40% by (estimated). His sustain also decreases, hence why many people deviate from a "pure" build to buy a Bloodthirster. Despite the additional damage from Bloodthirster, I still consider this build weaker than a "standard" ADC build for lack of critical strikes. It is possible to "hybridize" the Blue Ezreal build by substituting the Spirit of Elder Lizard (which is a horrible item IMO) with an Infinity Edge and buying a Statikk Shiv as your sixth item, thus retaining the increased poke damage from Iceborn Gauntlets and autoattack damage from Muramana while increasing overall damage through critical strikes and the Statikk Shiv chain damage. The crits are worth far more than 40 true damage by﻿ far. I have yet to finalize this build but I have had decent success in my experimentation.
