I just feel that blizzard won’t do justice by returning Nightelf lands, Atleast not putting them in a state nightelf players will like. Short of turning back the clock Teldrassil is gone and Ashenvale/Darkshore a mess of blight and torn down trees.
I know night elf players hate the Idea but them settling somewhere else might be better for the story in the long term.
The lunar event will have to include the Horde though so… don’t expect it all focused on Night elves.
