I don’t mind some activity in Silvermoon.
Especially after what happened to UC and Teldrassil. Pain is part of the drama, and since we play as folks in this video game world, it is part of a progressing narrative. Silvermoon is half in ruins, anyway. And the front lawn is little better as the Ghostlands. I am not opposed to losing in game locations due to revamps with lore basis.
It could be Alleria because of her heritage, or because of the Void. Or it could be an aggresive Alliance. Heck, maybe Yrel comes to Azeroth and she doesn’t think the Elves deserve the Sunwell because they are consorting with the Maghar. If Yrel takes out the MU Draenei who are currently guarding the Sunwell, that would be one way to get Velen off his duff.
Quelthalas is criminally underutilized and stagnant. There has to be something pretty big to get that place revamped. Bring it on!
