Yasuo has always been that tryhard champion, some can play him some dont but they all like yasuo he has critical strikes that just destroy you, some cool moves and alot of outplay potential, so here is a basic guide on how to play yasuo

Newbies to Yasuo:
Max Q as that will do most damage and scale with your ad & attack speed it helps you do your standart yasuo stuff and burst people easier

Advanced to Yasuo:
Max E as with that you will have more mobility in order to chase or escape aswell as doing alot of skillshot dodges and outplaying people

Flash Teleport Ignite those are the main summoners for Yasuo, i recommend Teleport and Flash as they will allow you to move more on the map and try to kill more people but if you are new to yasuo get ignite as you wont roam as much
