So in other words.. point A, point B, point A.Ashvane isn't leading it, nor is it hating on Jaina and such, its united and doesn't have an Old God worshipping cult in Stormsong. The Kul'Tirian fleet was found and whole it has been diminished it isn't just "Vanished" Zandalar has a new leader and while it has been damaged it doesn't have to deal with an abberation like G'huun(Thanks Titans) or Zul to be a schemy traitor. Azshara is free to do whatever she wants and not be chained to N'zoth. Speaking of
He got free from his prison which went as he wanted, and while he was defeated and or "dead". Xalatath isn't in the dagger anymore and she's elsewhere possibly in the Void and that dagger disappeared strangely enough. Nyalotha still happened, it just didn't merge with Azeroth creating this weird "insane" reality. Also Sylvanas is no longer the warchief of the Horde, she's kinda enemy #1 right now and we know where that leads. Oh and Saurfang is dead(Via Sylvanas). Sargeras sword is still stuck in the sword yes but it will be relevant again, something big like that isn't forgotten. If it was Blizz wouldn't of mentioned it in an early interview of SL(When it was first announced).
A lot has changed.
Edit: Forgot to add Teldrassil is burnt and well not a place to live, Nelves are kinda in this place of no home or at least a capital city/HQ to live in. Same with the Undercity and the Forsaken.
Also, your edit is unnecessary. I said "starting after what happened at UC"
