Yasuo, 100 crit no crit.
Alright so, I was playing Yasuo in ranked I had built both Infinity edge, and Statikk shiv. Whenever I q'ed minions with the 2 items I noticed there was no crit and the damage was a plain q/auto. With 100% crit I was not critting minions/champions with my Steel tempest or my auto attacks.
