User blog comment:TheTobarMethod/Umm Ezreal......so your a carry?/@comment-4794115-20121227231643

Before they got rid of the AS riduction on Essence Flux, Ez could stop most any other adc in the game. Being able to slow a carry's AS - which is what they rely on- and  increase yours is crazy.

Since they nerfed it, he hasn't been as strong, but his damage output is still nothing to laugh at.
