User blog comment:AtheistUntoDeath/Which of these Champions would win? Part 5/@comment-3072598-20140604103723

I've seen many people are getting confused here and focusing on the game mechanics.

First off, it was said that Master Yi had Psychological Advantage because he was not seeking revenge, this does not affect this battle because none of them seek revenge toward each other and both of them love Ionia in their own way, the only reason I could think of them to fight would be if Master Yi was requested to end the Ionian "Traitor" which for Yasuo would be just another day, making them even. Not to mention Master Yi would probably refuse.

Both Master Yi and Yasuo trained for a long time, but Master Yi trained by himself, Medidating and Perfecting his Movements, in order words he isn't used to train Practical Combat, which if you know includes Movement Prediction, Body's Resistance (Increased by enduring pain) and other factors which I'll not get into. Yasuo doesn't train, but is hunted by his former allies, which were trained with him and after he left and it is a fact that you improve a LOT when facing equals and/or people whose skill is close to yours. One more thing, though you may not notice, Masters have much less time to train, because they are occupied training others and in Master Yi's Lore is often said that he devotes his life to train his pupils. So I'd say Yasuo improved much more in his Lore than Master Yi.

Now to talk about Items, I once heard Master Yi's googles adjusts his vision to his speed, which I found to be the most plausible explanation (In his lore it is said most people wouldn't benefit as much from the googles as Master Yi, which increases the odd of this to be correct.), now what is certain is, it allows Master Yi to see a wider range of the spectrum that normal people see and it works as a binocular, I cannot define how wide is his range of spectrum, he might be able to see through things (And summoners might have prohibited him to do that as they did with Jax's weapon problem.) or he might just be able to see more color changes or night vision, or something strong like infrared, so I'll just ignore his spectrum since I can't value it's strength, I'll just assume that, as said in the rules, they are even, if Master Yi can see Yasuo anywhere, so can Yasuo. Master Yi also has a Katana which is a Light Dual-Handed Blade, what does this means? It means his weapon is heavier and slower than Single-Handed Blades but lighter and faster than Dual-Handed Blades. His Martial Art Wuju is a reference to a old sword style made for amusement, an artistic sword style which may explain why his training is alone. Yasuo was trained in god knows what with focus in Wind Techniques, he controls wind and wields a Single-Handed Blade which means he's so far Faster than Master Yi, he can also propels himself with Wind making it easier for him to dodge and even control Master Yi at a distance, since he controls Wind so freely his powers are probably limited by the summoners, because that wind shields could easily become a large area projectile which would slow down Master Yi (Air Friction), could also sufocate Master Yi with vast blows of wind if he tried to stand still or "Meditate", the only way for Master Yi to be faster than Yasuo would be if he were close to the Speed of Light but in that case his body would deteriorate everytime he tried to reach even close to that speed, because if there is no wind your movement is free of resistance there is no slowing down only gravity would push you down but the movement you be constant and acceleration would be infinite, which means yasuo could achieve any speed as long as he didn't try to go upwards. But if Yi was really THAT fast normally, he wouldn't have had such a hard time against Jax once he entered the League, since he's not even fast. So I'd say they are either Even in speed or Yasuo has the upper hand.

We cannot evaluate their Combat Skills, since they fought only different enemies, but we can evaluate their endurance, since Yasuo has fought more opponents of equal skill he probably has more endurance and if Master Yi loses a Hand, an Arm or a Leg, he can no longer use his so trained stances, while Yasuo could fight using only his head, his hand and his bleeding thorax, propeling himself or using windwalls.

So, my conclusion is, as long as Master Yi's googles don't explode the universe and defies all science towards speed, Yasuo's the winner by small advantages.

PS: I'm using only current information, Beta and Old Lores are ignored due to the possibility of outdated information.

PSS: Master Yi's Jerki... I mean "Meditate" will probably be too much risky since he must keep his Sword up and down. :ifyouknowwhatimean:

PSSS: Just found out about these debates, really cool idea, will probably come back next Duel and nice job making an even Match.
