Balancing of projectiel blocking walls
Namely: Yasuo's Wind Wall and Braum's shield. While these abilities perform well with the pesonality of the champion, their power seems troubling to me.
Many ultimates are projectiles, a lot of them also have a slow travelling time. I find it bothering how an ability with less than 12 seconds cooldown can stop an ultimate move of champion with 3 minutes cooldown.
This does not seem appropriate to me.
In my eyes granting these abilities a % damage reduction instead of completely blocking all damage would be a much better way to go.
