Can Ezreal's Q be treated as a crit?

the term "counterplay" means something you do actively while playing against the champion. it doesn't mean which items you choose to build. that is called counterbuilding.

Ninja Tabi already does what you want. It reduces all of the bonus damage from Ezreal's Q including the damage from Sheen or Trinity Force.

As for counterplay... you literally just dodge it.

If you're getting dominated by a skillshot ADC... I think that's just your fault tbh.

Dodge laterally, Never run straightforward. Basically play against him like you do Yasuo.

dang hes secretly a ezreal main with that buff.

Counterplay? You mean the thing where you dodge his abilities and he suddenly does no damage outside of his e and auto attacks?

Also yeah. Let’s let his q crit. Please. Make. My. Day.
