Did we need another Lupin thread though? The last thread was started almost exactly a year ago: http://forum.square-enix.com/ffxiv/t...ayable-race%21
I'm not against the idea of having more races. What I find is that players often make suggestions about another race without taking into either the lore or the technical requirements to do so. Lore-wise, yes the Lupin exist, but they physically exist in the same way the Ixal, Amalj'aa and Sahagin exist. They use the exact same Hyur animation rigs the players use. The Sylph and Moogles use the same "floating rig" and thus their attack animations aren't that different. The Tonberries and Namazu, aren't that far off the Lalafell's. So when people suggest a race that doesn't fit something that is already in the game, it requires a lot more animation effort than reusing an existing rig. A proper playable Lupin would have the same requirements as making any of the beast tribes that don't wear shoes playable. Mainly the animation cycle and the existing gear would not work.
The devs put a lot of effort into the individual animations for each race, so any additional race that can't reuse 90% of an existing race's animation is going to be very expensive. That's essentially why we only got two added for ARR (male Miqo'te and Female Roe) and the two for the Au Ra with HW. With that, those race/genders re-use most of the animation sets. Hence if the Lupin were to become a playable race, Just like the Viera, or some other humanoid, they would likely end up being variations on the Hyur or Elezen, and because the Lupin trend more "furry", the animation for the head would be harder to pull off than the Viera. However if they put effort into the feet/legs animations for one, they could reuse it for the other. Otherwise the largest way to cheese this requirement is to make the all foot gear for Lupin/Viera permanently attached like the heels on the female gender races. Hence they would end up walking like them, and while being less interesting, it saves animation budget.
From a lore point of view, the Lupin do not (yet) have a primal. However based on everything we know about the lore for the Doma area thus far, is based on the three relics of Japan, the Sword, Mirror and Jewel. Susanoo is the god of summer storms, which we wound up summoning at the Red Kojin's treasure room. Tsukuyomi is the god of the moon (summoned with a mirror), thus leaving an empty slot for Amaterasu being summoned.
Take a note of what Amaterasu looks like in Final Fantasy Dimensions II:
Like we likely haven't seen a beatman primal for the Lupin because they're saving her for later. But the devs could also mess with us.
