Since Lordaeron is rebuilding and Forsaken can now be in Lordaeron
And Tyrande have a seed of anima but the tree of Teldrassil is burnt
Ashenvale is completly taken by the horde and goblin taking the woods
Darkshore is plagued
Hyjal is a peacefull neutral place
Stonetalon has been bombed in Cataclysm
Desolace is full of centaur and managed by the Cenarion druid
Moonglade is a place reserved for the druid
It mean on Kalimdor there’s only 1 place left true and mighty : Feralas with Feathermoon Stronghold.
We saw the Night Elf winning against Naga invasion and since there’s a island away from the land it may be possible the seed tyrande have can be set here ?
Feathermoon Stronghold is also a huge reference to Warcraft 3 with huntresses, tower, A real army and can be a good place for capital city if there’s a bridge with the island where you can get bank and auction house and a port.
in term of defense we can also understand the lore in Warcraft 3 and the Mountain giant and their alliance with the Night Elf .
That would be a dream place, oh and there’s a gateway to the dream nearby so Tyrande can see Malfurion more often
