Yasuo change idea

Have flow directly linked to the windwall. Remove passive shield, boost Yasuo's base hp or hp regen to compensate.

New passive- Flow = windwall HP, for every projectile that hits the windwall, Yasuo loses 5/4/3/2 flow (scaling down with levels of his ulti, so at level 1-5, at 100 flow, Yasuo can block 20 projectiles, level 6- 25 projectiles, and so on) if he reaches 0 flow, the windwall breaks and Yasuo has a minor recoil for having it break (Can not build flow for a while, and a small slow/some damage)?

Also give him dis: http://www.zeldainformer.com/images/articles/linkswordbeam2.jpg for lol's At 100 flow, he can shoot a short range 'sword beam' with his autoattacks. Something around 1.3 of his 1st and 2nd Q range?

This would give him more reason to think before throwing his windwall out, as there would be a downside to it if overused or misused, while also adding a little 'minigame' with the sword beam added to his kit. Rito likes minigames..right?

And add a real cost to at least one of his spells, other than just free-cast with cooldowns.

Edit: Also have some projectiles count for more than one, like ultimates such as Ashe/Jinx/Ezreal's count for 10 or so?
