DAMAGE OFFTANK YASUO
Hello, im a Diamond 5 Yasuo main, who just wanna show you my way to play Yasuo in the Preseason. :)
Runes depends at your playstyle at all. If you wanna pressure your lane early, you can focus on putting as much Attack Speed as possible with MR, Armor and a little AD in your runes. Otherwise I recommend Armor and MR so u don't fall off in early roams and when you are getting ganked.
Nothing special, just take whatever you want; the important things are the Keystones.
I highly prefer GRASP OF THE UNDYING and WARLORDS BLOODLUST, but if you want: FEVEOR OF BATTLE is an oppertunity.
