Just make Yasuo's thirdQ and windwall cost % flow,windwall duration scaling with the amount consumed

Seeing as how Yasuo's winrate has stabilised I do not see that happening. Regarding the idea, it is poorly thought out. The fact you are dependent on a resource you have 0 control of due to the fact you cannot manually activate the shield or manually generate flow (a la Rengar) promotes a degree of randomness when it comes to nearly his ENTIRE kit that would make him wildly inconsistent and would also promote him to have to build extremely tanky to be able to trade with nearly the entire champion pool.

Just because Yasuo possess' a windwall does not mean the shield has to be discarded; facing Zed or Talon for instance (even diana/ekko for AP) even if they use their blockable abilities, their AA's with steroids still hurt substantially and they also have tools to disengage that are not as situational as Yasuo (because the entire game does not happen only in lane with 300 creeps). Also his base stats are very bad, so even if those changes would go through they'd have to be buffed INSANELY high, and then you have Triforce/FM Yasuo again.

Just my thoughts.

Sorry but that would kill entirely Yasuo. He struggles a lot in this season 7 meta already (very tanky colossus toplane users-long range midlaners)

a Health meter on the windwall so it functions much like a targeted directional shield that only blocks a percentage of the damage instead of fully negating 100% of the damage of a projectile.

Dont think its good on his q but definitly a great idea for his windwall. Creates clear windows for counterplay, removes a bit of the frustration of him having both having his shield up and the windwall but still leaves it intact to make good plays and succescases . He can then still put a quick windwall halfway in the fight to block that big attack if he is quick enough but no longer the entire tf blocking wall if he hasnt builded up his windflow or placed it at the start of the fight strategically. Even thematicly this makes sence because instead of the winds protection him for a bit he uses his flow for the wall. More flow -> longer wall. I would however wait for him to become dominant again to put in this change because else they will have to buff him somewhere else and fuck that ;p

Thoughts? Well my thoughts are this is my idea except worse because it randomly includes his third Q... i commented this idea like a couple hours before you posted this...

You didn't really explain or include any information as to how or why this could work. This would open up room to actually buff Yasuo in the correct places where he is suppose to be strong. Making Windwall less reliable or easier to punish is the point of changing it, it has nothing to do with his third Q which has the counterplay of dodging, plus it requires setup.

Making his third Q cost flow is definitely interesting. It could work tbh, that'd be cool

Or mana.

Make 2 spells cost but the rest don't? Makes perfect sense. He was made as a resourceless champ. Keep it that way.

Just stop making posts about Yasuo.

he doesn't need any changes and certainly not all these terrible suggestions

Having Yasuo's Q cost Flow at any stage would very likely make him feel a lot clunkier and less functional, without actually giving him any more counterplay. Having Wind Wall consume Flow might be better, since it's meant to prevent shots from reaching him anyway, but it might need a bit more work than just slapping on a Flow cost.

I feel another solution, which could be combined with a flow cost Wind Wall, would be to make the wall a lot narrower and shorter-lived, but instead reduce its cooldown significantly. That way, Yasuo would be able to block more projectiles reactively in fights, but wouldn't be able to flat-out negate the entire enemy back line for 4 seconds at a time.

Make his shield duration lower so it is more reactive rather than it being 3Faceroll5Me

Yeah let's make his abilities cost a resource he has no control over.

Honestly, making it so his Q (especially the 3rd one, like what the hell?) doesn't apply on hit effects would be a more than sufficient change.

I always thought it would be a better idea to give him a regular kit scaling so that his power doesn't just suddenly spike mid game and then grant him a proper amount of AD scaling to make his early to late game more linear. They should also give an incentive reason to use his windwall outside of panic blocking ranged abilities for example Poppy's W grants movement speed and resistances.
