Just theory crafting... What if we change Flow from giving a shield to giving full damage crit?

That way he can still be poked and can be pressured into jumping on his target.

But if he keeps dodging, he keeps getting stronger.

First hit after Flow is charged that happens to be a crit will deal full crit damage. Any crit damage dealt while Flow isn't charged deals it's regular reduced damage.

I've also wondered if increasing the cooldown of Windwall, but making it so that the more Flow Yasuo has, the faster it recharges would work for the better.

Good idea? Bad idea?

Think it needs tweaks?
