Yorick's Q On Turrets, Why Doesn't it Work
Yorick's Q should be working on turrets. It's an empowered auto, and thus it should work like Nasus' Q, Darius' W, Garen's Q, and Morde's Q procs.
In the champion spotlight, Yorick's Q is seen working on turrets multiple times, during this time onward.
But in game, pressing Q procs sheen, but does not use the Q active.
