The actual problem with yasuo
Disclaimer. I'm not saying he is OP in any way shape or form, but he's gathered a lot of hate and I'll give my input as to why I believe he can be oppressive at times..
His e. Not the mobility part, but the damage. Versus a squishy mage, he can just max E and do ridiculous subsequent magic damage to them over time and starting E at level 1 then aa'ing the enemy mid just instantly seems to put them at half hp.
Why does yasuo's e do that much damage? why is it magic? heck, why does that shit even DO damage to begin with? If it didn't do damage, you could probably give him some love elsewhere honestly..
