'Eorzea' Used Incorrectly?

[Shem]

It seems to me that many speakers in the new areas under the map heading 'Far East' use the word Eorzea in conversation when they should be using their own region (or Hydaelyn) instead.

Isn't Eorzea mostly just Aldenard and Vylbrand? It doesn't make sense for an NPC in Kugane to refer to a group as the best alchemists in Eorzea, or for a Doman to describe a tiring task as running half way across Eorzea.

I made specific bug-reports in game, but am I crazy, or are many of these NPCs (and the writers, by extension) misusing Eorzea? I know a lot of players incorrectly use it to refer to Hydaelyn, but it seems weird that such a mistake would also show up in dozens of new quests.
