>>130I can't imagine the number is very big. Last I checked, WoW was still hemorrhaging users. Since there really isn't any advertizing to speak of, I'd have to assume that the way most people are finding out about WoW is through word of mouth and then joining because they feel like they've missed out on playing or something. Wouldn't surprise me if the number of people still playing Overwatch is greater than the number still playing WoW, to be honest.
Also, I recognize that artwork, but I can't possibly remember what it's from (other than that it's a doujin, of course) and it's driving me a little crazy.
