Emerald Dream - Good for another "big continent" expansion like TBC or WoTLK, and there's plenty of story to develop there around the Emerald Nightmare and the Green Dragonflight (notice also out of all flights, green is nowhere as a mount and Oculus doesn't really count) - in lore it's just as big as Azeroth so it would be really stupid to make it a raid or 5-man
Argus - Draenei Homeworld
Burning Legion Homeworld - wherever that is...
