I'm so sick of Blue ezreals to the point

I hope you get punished appropriately.

Blue Build Ezreal has it's place on kite- and poke-oriented compositions.

The main issue is Ezreal building it when his team is relying on him for damage.

Pretty much every adc change for preseason made standard adc Ezreal builds weaker. Essence Reaver no longer gives him mana back for physical damage. Sheen and Trinity Force no longer give him AP. All adc damage items lost AD.

Blame Riot for making blue build the best possible option for him.
