Ah, all my bad then Dx (went and doublechecked the same video before posting as I also hadn't watched it in years but didn't realize there was another take at the end). Sorry!
I for one will likely quit the game if they were to give an alliance thing to the horde just like that (blue eyed thalassians having been an alliance thing since vanilla), not that I expect many others to do the same, but I'm sure it'd be a sizeable shitshow regardless.
