My proposed Windwall rework:
-Windwall is now stackable up to three times. Yasuo cannot be any more full of air.
-Windwall lasts for 5 minutes.
-Windwall now has block charges. 2/4/6/8/10 ranged attacks may be blocked.
-Windwall now recharges blocks. 1/2/3/4/5 per 5 seconds.
-A Windwall cast on another Windwall causes it to bounce 2/4/6 Yasuos in that direction.
-Enemies who run through Yasuo's Windwall have a 4/8/12/16/20% chance of being knocked up.
-Enemies knocked up by Windwall may continually be knocked up, RNGeesus willing. Don't try to walk through walls.
...
-Women knocked up by Windwall may collect child support, lowering his gp10 by 30%
-Women knocked up more than once may stack child support debuff on Yasuo.
