User blog comment:Willbachbakal/(Item Concept) A New Kind of Crit/@comment-24385282-20150702171703/@comment-1330314-20150702181615

I covered Yasuo in the Champions tab in the above blog post: the main idea is that he gets to naturally crit every other strike, rather than every three strikes, and would therefore be able to crit on every attack with IE. I also tweaked his Q to preserve its crit synergy, though that's likely also something he could probably afford to trade off in exchange for more streamlined kinds of power.
