If by fixed, you mean gutted. All of these changes together would gut him, and that isn't what I want. I want him to feel fair to play against, and him having a wall that blocks all projectiles to dance around in a 1v1 situation isn't fair. If he comes to the other side of the wall after you walk through it to get to him, why are you punished for doing so? He's a skirmisher who makes people have to fight on his own terms 90% of the time.
And to me that's what makes Yasuo such a frustrating champ to play against for people. Very rarely do you ever feel like you're in control of the lane. You have to be a hard counter like Riven or Malphite to feel even slightly secure in your lane. Yasuo never has to fight on your terms because the odds are always stacked in his favor. He can dash to an unsafe part of the lane, hit you a few times, and then fly back to the starting point, doing this over and over, whittling your health until he eventually just goes all in and kills you. And that's just in top lane. I pity those poor mid laners who can't land anything on him because he dodges everything, and then they get killed at level 6 because Yasuo's powerspike hits much harder than their's. Hopefully the nerfs this patch actually make him feel more fair
