Hmmm. Don't most items on the Mogstation (excluding the event items) disregard the lore of FFXIV in some way? I feel making Viera a Mogstation race would make it impossible for them to have any kind of lore in FFXIV's world (heck, I can already imagine the description for them making reference to FFXII or Tactics Advance: "Play as the mysterious Viera race from FFXII/FFTA"). While I'm still against the addition of Viera overall, it's better to make them a part of the games world and potentially available as an expansion bonus rather than plop them into the world with no lore or anything to make them interesting/appealing outside of 'appeared in this other game.'
