Ezreal is more fun as a mixed damage burst mage than he ever will be as an adc.
He has more itemization, more damage at a way higher range, more access to cdr, and is way more high risk high reward.
AD items nowadays are not made for Ezreal. He can't utilize crit as well as any other adc, and the items he can use are steaming garbage (Looking at you
).
Nerfing his AP build into the ground was equal parts unnecessary and dumb.
Also, I'm not talking about when he was abusing that ap jungle item back in the day, I'm talking about regular ol' ap ezreal.
