Hello! everybody. This is my third build after 4+ months. I don't know how to make that good chapters but, i can put some tips and stuff.

CONS

Too squishy.
Rare use E.
Not good combos.
Can't carry :3.
Difficult to play.
Not that kamikaze.

PROS

Much skill, such wow.
High-mobility Damage.
Too much damage with every spell. (Especially with E)
Good ulties in teamfights.
Can carry ^^.
Makes the enemy confused and boring to play against.
Such running through um.. players minions dodges etc.

Farming with Yasuo, is easy. You can use E to every minion of the wave do dodge the enemy abilties and stack it 4 times so it deals more damage when you use it to champions. After 4 stack and have Whirlwind on, you can use E-Q dash and Ulti for the ultimate damage and then you can chase him if he hasn't died. In teamfights, try to ulti at least 3-4 people.
