Whether or not it is intentional to block the passive from being used even if Quinn walks around the wind wall and attacks again, it is still very annoying because it leaves the ( harrier ) Mark on Yasuo even though the passive was either blocked or not.
TL:DR Wind Wall Breaks Quinn's Passive From Being Proc'd. Before OR After Wind Wall Isn't In the Way.
To Quinn players this is actually a very serious bug because most of her damage relies on using her passive.
