How is this a headcanon? Visit ICC and see for yourself that the mobs are called Darkfallen Classname and “The San’layn” is put in the title field. Of course my analysis of the BfA quest and such would involve some headcanon because of the extreme lack of official information on them, but I’m at least trying to provide evidence and proofs when I stand for something. You just throw random facts and call it a day
