As much as I would love playable moogles (A look at my sig would reveal as such), I do realize they wouldn't work in this game for reasons others have stated. It just wouldnt' work lore-wise. In addition, they would likely have to be a form similar to the Ivalice version, to allow for weapons and armor.

Now, if there WERE a race of Ivalice-style moogle adventurers from a far off land... well, I still have like three bottles of Fantasia stockpiled for the day.
