Hey Sirus I looked at your guide and I had a few things really just to say. Im not a high rated player just thought I'd tell you what I thought of yasuo and how I play him because hes one of my favorite champs right now. I looked at your build and there are some things I agree with and some I don't. For example you say to not take last whisper but I find that to be a great item with him. His ult(if I remember correctly) once used on a champ makes it to where you ignore 50% of their armor, combine that with last whisper and youre basically ignoring 85% of their armor straight off. Which for some tanks is pretty amazing for you and =dead for them. You also had infinity edge as an item you can get if you want but is super key for him in my opinion with more crit strike chance and making his crit strikes do more damage. My final build is usually something like berserkers greaves+stattik shiv+infinity edge+blade of the ruined king and guardian angel, then the last item just depends on the game. If they have a lot of ad I would get maybe randuins plus its active is an aoe slow. Very nice for him. For more ap then malmortius for more ad/mr and its passive shield. Although a lot of the time I will go with frozen mallet for better chasing and more health. Again this is just my opinion and my preference for 5s. Sorry my comment turned into a rant. Fun gaming everyone.
