Ideas on yasuo's balance (Wind Wall idea)

TL;DR: Reward good use of Wind Wall, while nerfing a missuse leading to a more healthy ability and in turn leading to more healthy kit. Wind Wall's simplicity makes a pretty annoying ability practically impossible to balance. Especially for all ELOs.

Yasuo, historically, has been very difficult to balance, hence all the nerfs and consistent bans, regardless of said nerfs; reasons seem to fluctuate between "annoying to play against" and "he's strong". I think there is a very simple way to add even more skill expression in his kit, while also adding balancability and reducing the "annoying to play against" part a bit. In my opinion, Wind Wall is the source of quite a bit of this frustration due to the fact that it's just a giant wall that blocks every projectile for 4 seconds - he just puts it up and walks around it, often leading to a game of "ring around the rosie" in lower ELO. I think there needs to be more to this ability, as its simplicity makes it harder to balance. My idea is something along the lines of reducing its duration to 1 second (less than live), but if it blocks an ability, allowing it to last the full 4 seconds (live's value). This would add more skill expression because the player’s timing would have to be a lot more reactive than proactive, and you'd be rewarded for using the ability properly, as opposed to just putting it up because the enemy team “might do something soon". The ability reminds me a lot of Fiora's Riposte, which only lasts 0.75 seconds because there is a reward, if used properly, leading to a more healthy ability. I think if Wind Wall gets the same treatment, it would also become a more healthy ability.
