The Night elves should secure Feralas(with Eldre’thalas and feathermoon stronghold) as their new homeland
Gilneas and Kezan should be reclaimed by the worgen and goblins. Bilgewater harbour city could alternatively just have the capital city essentials added
The mag’har should get the underhold (why so lazy about this allied race, Blizzard?)
The forsaken could claim the ruins of stratholme or something, maybe scholomance? Idk, something along those lines
The darkspear were never much for cities, but they should have their own spot in Zuldazar like the other tribes
Gnomes, gnomeregan, obviously
