Those are some pretty crazy ideas. Lorewise, an agreement with the Horde was made and they will keep away from Ashenvale. Even though Night Elves are fierce and savage, they will never stoop so low to hang Orcs from trees and create a huge bloodbath.
As for Dalaran... Why do you want it to be rooted? It can float like a giant aircraft anywhere Jaina wants to, and then relocate it once a new threat arises. Why should it be static in a swamp?
Something should happen with Gilneas since Varian says that is the Alliance's next move, and Worgen need some story, as well as a place to really call their own.
Stromgarde: I want to see it retaken by the Alliance, but not as an act of the High King, but as an act of Danath Trollbane, since Stromgarde was his city. Butt hat is not really a pressing matter, so I can live without it.
Orgrimmar is said to receive the changes to reflect on the Siege. So I am glad for that.
