I personally much prefer the traditional, FF9/FF14 moogles to the Ivalice ones. Moogles are supposed to be weird inscrutable stylized creatures, not realistic-looing raccoon-bunnies!
Moogle:
NOT MOOGLE!
(not in the spirit of the real, traditional FF moogle, anyway)
And maybe WAY down the line, like in a future expansion in 2015 or something, they could add playable moogles, or temporary moogle-form transformations. BUT make them play very different from humanoid races. Like they don't have the same classes and they do something else than the humanoid races do. Mail delivery quests, spirit negotiations, moogle battle mini-games, etc.
Come to think of it, I hope there's lots of Moogle involvement in FF14's future Gold Saucer.
