just as a quick sidebar:

correct me if i'm wrong but the first reference to "Doma" in the FF series was in Final Fantasy 6. This is where Cyan was from and he was a Samurai.

Since this game seems to draw references like this from previous FFs, it stands to reason that Doma in ffxiv will follow suit with the "far east" style classes and content.
