Yasuo Q weird

tornado, is not blocked by passive, which i find weird since, his tornado also applies hit-on effects, such as thornmail. Another thing is that, if a buys , his q would not prolong the duration of the 8 stacks of but would still apply the aoe. q also does not generate stacks for . Even though q is treated as a basic attack, and says basic attacks prolong, generate, the stacks, and apply the aoe. SO if a does buy , it would only apply the aoe and magic dmg.
