Windwall change
What if instead of absorbing ranged abilities it stops them, and if they have an after effect such as Galio Q, or velkoz Q the effect still goes off.
Example, Yasuo windwall's ashe arrow, but he does it at the last second, instead of the arrow just dissapearing, and instead of yasuo getting stunned (since it technically didnt hit him) he still receives the AoE damage from the ult and the slow but not the stun that normally would have occured if the arrow had him him directly (since it hit the wind wall instead)
Compare to: Yasuo, he can tell the enemy ashe is gonna fire her ult so he wind walls early, the ult strikes the windwall but he is far enough away that the ult fizzles on the windwall.
This would allow Yasuo to still stop projectiles, but leave abilities still able to give off their special effects. Compared to braum who takes damage, and effects from abilities he stops, it seems like a step in the right direction to improving yasuo's in counter play with projectiles.
It rewards being preemptive and knowing your opponents over just straight .01 last second reaction time to negate all damage.
TL:DR instead of wind wall wiping abilities off the map, just force them to explode upon impact yielding their effects as if they reached their intended target or impacted a champion.
