The only Disaster about Yasuo is...
Why doesn't he have mana? Let's look at his kit, i have no problem with anything he does but why doesn't he have mana? in 2011 xypherous said that riven being manaless is ok because "her gameplay requires a lot of positioning, cooldown and stack management" but what yasuo has to manage? literally nothing but spam E and Q every second in laning phase, doesn't manage cooldown, nor positioning.

then xypherous said that riven has to fight to win the lane, which means that it's high risk high reward. Again how is this possible with Yasuo? he dash--> Q ---> dash back and shield a part of your damage, throw tornado from miles away every 8 seconds without forgetting the windwall screwing one of your projectiles every 24 seconds (like ahri's Q) forcing you to waste even more ressources.

he did a full list of everything possible in league, managing mana,energy, health, fury,cooldown.. WHY ISN'T YASUO BELONGING TO ONE OF THEM? he doesn't have ressources, but he also doesn't have cooldown, like... what?
Just think about it
