Well no it wasn’t an expansion, but I’m sure if someone said before BFA that Blizzard would have a patch where half it is dedicated to Azshara and Nazjatar, and the other half is dedicated to a secret Gnome city, you would be saying the same thing you’re saying now about a Goblin/Gnome expansion.
Yeah, but again, Catsclysm revamped the entire world, and still got 6 new zones on top of it. I’m simply saying that a revamp of half the Eastern Kingdoms would be rather strange, unrelated to the dragon isles, be insufficient, and also wouldn’t be eluded to in 9.2.5.
