As A S8 yasuo main
Yes. He needs nerfs. Listen riot, during the crit item changes (the true damage ie) it was literally a meme to say yasuo was broken. I was able to perform a 60% winrate on him in over 50 games (but that was because I played him to the fullest extent anyway) but now that Yasuo is quite CERTAINLY a broken champion, its time to ner- wait no.
Rework Yasuo in some way.
He reaches all the requirements to be reworked: S5 (or older) champion, pretty hard to fking balance, etc. Now riot listen to me carefully when i say: REWORK ONLY HIS W, OR HIS SHIELD PASSIVE.
The key to keeping Yasuo players is keeping the fun and enjoyment, and outplay potential he has. Removing his wall and changing it, can either grant more healthy outplay potential, or not. Hell for all i know his W COULD be the new shield, make it something like: After activating Yasuo gains 20% tenacity and some 50/100/150/200/250 +AD +AP shield or wtvr. Just something. He needs that ability changed. Its the only way.
