Just trying to say that HS does seem to actually be a thing in WoW. Certain npcs talk about playing it and such. So saying cool things like gnome druids are in hearthstone gives them a foot in the door cause it means someone in WoW is at least curious enough about the concept to make a card, saying "it's in HS therefore it should be WoW canon" like a guy a few quotes ago was doing is too far imo.
