Since we're visiting the place again, I just thought it would be a nice "excuse" for a nice callback Qiraji mount. Maybe not necessarily black, if people are too touchy about it. :P
As far as the original event is concerned, if they want to keep Classic realms as a window into Vanilla, I think they should make the Gates event seasonal, with no mount reward - that way people can keep experiencing it more than the one time per server, but there's no issue about cheesing the exclusive reward.
