Well… I have often bleated about Alleria assaulting Quelthalas, and dooming it to the Void.
And then we can have Quelthalas as some Void Scarred Hellscape to half way reclaim, as our bastion in the invasion of the Voidlands.
The High Home has seen much devastation, but it has enough renown to carry the franchise a few yards further.
And Blood Elf lore is what the real people want. Orcs, Humans, Forsaken, kaldorei… just hiccups in the tale of the Blood Elves.
