User blog comment:NicknameMy/Rework for Master Yi/@comment-3493296-20111102055009/@comment-50.82.174.147-20111105222915

Tryn used to get 1.3k crits on champs with 100 armor. What Yi would get with double damage strike is a bonus 100% crit damage essentially. Tryn got what, like 48% bonus crit damage before his rework. Enough AR pen and the most armor many squishies have(or get) becomes nigh useless.
