User blog comment:AtheistUntoDeath/Which of these Champions would win? Part 5/@comment-1272757-20140606100642

I would have to say... Yi. Both of them are specialists in their respective styles (Yasuo being a prodigy, Yi being a trained and true master), but to be quite honest Yi just has a great deal in his favor. Yasuo wins through sustained fighting, becoming more dangerous as a fight goes on. His Steel Tempest requires time to prepare in order to launch his whirlwind, which must hit in order for Yasuo to use the most powerful technique in his arsenal; Last Breath. What's more, aside from his incredible skill Yasuo is entirely a normal human being (by Runeterra standards, at least). The only real thing he has in his favor is his shield which is periodic and only absorbs so much, and his ability to regularly land viciously precise strikes (aka crits).

Now Yi, on the other hand, is a very different story. He wins fights by rapidly cutting through his enemies as swiftly as possible. Where Yasuo can get one strike in Yi could easily get two. Yi can strike opponents faster than they can track him, allowing him to evade a great deal of damage through sheer speed. His Wuju Style also allows him mystical abilities that Yasuo's does not; by simply making distance and meditating Yi would be able to easily mitigate or even invalidate any damage Yasuo has dealt. What's more, by focusing his power through his blade he can cause incredible damage, and further focus allows immeasurable damage capable of striking through any material or defense with ease, causing grievous injuries that even Yasuo's strikes can't match, though it can only be used for a very brief period. And finally, the epitome of his Wuju Style allows him to move and strike with such speed that Yasuo would just be utterly outclassed.

Yasuo has higher damage per strike by default, more defenses, and a ranged technique that can lead into a highly destructive technique. But in terms of speed Yi is in a league (heh) all his own, allowing him to weave past any whirlwind and launch a severely injuring strike before Yasuo could properly react. Any damage Yasuo does manage Yi can easily buffer or heal off, and can retaliate with damage Yasuo has no means of mitigating before proceeding to launch strikes several times faster than Yasuo ever could, with speed that Yasuo could never escape from.

Ultimately it comes down to the differences in their styles. Like the wind Yasuo must slowly draw power and build up before striking out like a force of nature, but with Wuju Style Yi can weave through the raging storms and strike at its center, and do so basically at will. Yi's fluidity and speed just give him the advantage to overcome the power Yasuo wields.

So in my opinion:

Victor: Master Yi (Victor-Yi?)
