Then why does it have a flag? pretty much every main city before hand had its won flag while endgame hubs didn't. Plus Eulmore has its own system of government, an associated territory (Kholusa, granted that would also apply to Revenant's Toll and Idyllshire), a second and third area and other things that would normally be expected of a City then an endgame hub.
(Agree on the Crystarium though)
I feel like this is a stealth request for instanced housing :P
Regardless, It would had been rather strange for an entirely building to windup in another world
