Yasuo's Passive is what makes him Overpowered
You are against Yasuo, you don't want to feed him so you stay back taking what CS you can get under the tower. Meanwhile Yasuo farms with impunity. If you poke him he doesn't care, all he has to do is move to generate overshield of significant power. He also has double critical strike chance from his passive so he is an assassin. So if you venture out to engage him to trade, he wrecks you like any assasin can. Ranged wont matter, Jinx is not a counter. If she is close enough to hit yas, he is close enough to zoom in and destroy her like any assasin would do. So comes level 3, yasuo gets Phantom dancer. Now his trit chance just went up to 60% per auotattack and the item grants him attack speed at 45% bonus as well. So he is hitting twice as fast and has at least an above 60% critical attack chance at level 3 or 4 and with another brawler's gloved to build statik shiv he now has an 80% chance to critical trike WITH an overshield built in. He didnt have to buy bloodthirster or another item to get it, he gets it by just moving. What is more, the shield never decays.
Yasuo: Classification: Hybrid Tank and Assassin.
He has all the death dealing power of Alkalai with all of the tankign power of a mid range melee champ like riven. At level 6 he can 1v5 your whole team and come out with 4 or sometimes even 5 kills. You cant melt through his HP unliess yo ucan keep him permanently rooted and stunned and then with Phantom dancer he can move through all of you and just run away if he gets low, though Yas rarely does because he can just waste 3 or 4 of your entire team and then if he dies, no biggie because he traded 3 or 4 v 1.
Solution: Riot needs to decide if Yasuo is a tank or assassin. His passive should either be the critical chance or the shield but definitely not both. Yes, I know the Yasuo mains will vote this down and flame me but the Ban numbers don't lie, the KD ratios don't lie. Currently the only way to shutdown Yasuo is to hope they are a bad Yasuo player or simply dont even contest the lane, just abandon the lane.
and be perfectly safe since he has 2 extra item slots with 100% crit.
