Blue Ezreal isn't a carry build, it's a poke-and-kite build. You will never match the straight up DPS of a typical ADC build, simply because you lack the multipliers for your damage (crit chance/damage, attack speed, etc.) What the Blue Build offers is ridiculous stat-efficiency, and virtually unparalleled kiting ability. With the 39% CDR you gain from this build, you can effectively spam Q's to reduce CD's and arcane shift rapidly to reposition - either offensively or defensively. BotRK, Muramana, and Iceborn Guantlet synergize with his Q's spammability, and turn the annoying poke spell into a highly threating nuke with an AoE slow and % health damage. Its effective in solo queue because teams generally lack the coordination to protect their own ADC, as well as the coordination required to successfully pin down a kiting ezreal.
