Yasuos kit is optimized for his earlier playstyle, not his new one
The reason Yasuo is packed with ways to kill players under tower, live harass and block ranged skill shots is because he was designed to be a mid lane assassin. The current Yasuo is a bruiser with every safety window open for assassins. Giving bruisers as if they are an assassin has always turned out wrong, but with Yasuo he changed into a bruiser due to a better build path and the new conquerer keystone. If riot want to balance Yasuo, they need to target the ways he is able to assassinate and optimize it into ways he can 1v1. This would explain why Yasuo has a good early game(assassin properties) and a good late game (bruiser properties). Just my thoughts on the Yasuo hate train.
