Yasuo is a skirmisher and just like all the others,
He has ridiculous steroids in his kit to make him function properly as a melee carry, or a skirmisher.
(other skirmishers include
and the binary underpowered ones are
)
So yeah. Stop complaining about his kit, especially when it is incredibly idiotic gibberish (comparing his passive shield to the gnar bar). if this is indicative of an inherent issue in the skirmishers class then we shall see, but for now, YASUO GOT NERFED. STOP WHINING.
