An idea for a Crit rework

Replaces Critical Strike Chance

Critical strike causes every other autoattack to deal bonus physical damage equal to a percentage of their attack damage, increasing by the amount of critical strike they have(for example 20% crit would mean they deal 20% of their ad every other auto) this effect does not benefit from lethality, armor penetration or onhit effects.

's passive would be changed to, unlike other champions, he benefits from critical strike every attack, and his Q and R scale off of his critical strike in addition to his attack damage.

Is this dumb or no?
