Odyssey Yasuo is another "Pay to Win" Skin
There are a few skins that give very obvious advantages, Steel Legion Lux for example. Odyssey Yasuo, I believe, is in the exact same boat.
Laning against Yasuo, his tornado typically has a VERY distinct sound when it is ready. In the Odyssey skin, there's still a sound, but it is FAR quieter and less of stand out sound compared to the normal.
Also, why did the tornado shrink? Odyssey Yasuo's tornado is half the size of a normal tornado, but has the same hitbox. Why is this ok?
