I mentioned Ashe and Cait because, if I understand, the PRD generator is basically a guaranteed crit based on X attacks, so I assume it can be taken advantage by either not attacking for a certain period of time (Ashe) or attacking a number of times to achieve the bonus damage (Cait). But, that bonus is still heavily based on chance because of the suggested evasion mechanic, so we're back to square one.

Crit chance based on health still seems flawed to me. To elaborate on my earlier point, say you and another ADC both have 15% crit chance based on the other's health, one of you might get a crit, even several, while the other gets none. Further still, say both' 'of you do get crit procs, but the other player gets several and you only get one, then that one crit is negated by the evasion mechanic and you lose the fight. Still too much chance.
