As a sidenote myself Blue Ez is a high level build. At normal level people focus on building damage or insane tankiness while lightly investing in utility and wards.

High level this is the opposite. At high level damage means alot but utility and surviving to deal consistent DPS matters more. So Low CD's, kiting, tankiness, tons of free flashes on E, high penetration and %'s to deal with bruisers, all this fills out high level fighting mechanics.

In sliver Elo this is useless, at silver you wanna instagib people nothing more. THATS why Blue Ezreal doesnt work for most people. More evidence can be seen here
