I would fully support and religiously watch a FFXIV anime because let's face, Tataru with big anime eyes would be pretty much the greatest thing to ever happen in life. as for the story it could either follow the various NPCs we've met on our travels, or it could focus on something like following the scions while we're out doing all their dirty work for very little pay.
or any number of ideas that could make it work.

hell they could even make it a high school comedy where the scions are an after school club :P
