This isn't the yasuo passive rework the boards Wants, but it's the one they deserve

No longer gets double crit chance

Now gains 20% crit per death

after 100% crit, now gains 10% crit damage per death to a max of 50%

can no longer build crit items

May only get up to two stacks per enemy champion, to fully unlock his power he must die twice to each enemy champion (enemy assists count though but he only gets one stack per death, so he has to int bot lane four times)
