I happened upon the Viera thread today, and it was quite interesting.
However, I do not see it being ever possibly implemented in this game, for many reasons I will not individually list. The simplest way I can sum it all up is that, in the end, the "Viera Race" as a "logical construct", is not very valuable, has too many flaws and logical weakpoints, which outweigh any benefits it may claim for this game.
So I took a shower and, building upon another feature I was envisioning, think I may have an alternative, and a solution, for this. Also, the Viera thread did say "make your own race thread".
So basically, this new race would be ... "Garlean". (Save the gasps ... I know how this sounds.)
1. Unable to use aether-based magic, and thus have no mana.
2. Different from Hyur, facial features are more gritty and realistic to real-life, than Hyur. Their temperament, I imagine, will be the "coodere" kind. (Think Ghost-In-The-Shell universe in both looks and personality.)
3. Does not wear armor, but instead will have 2 slots for each body-part, one is normal clothes, basically just plainclothes and without stats. The other is some kind of "magitek exo-armor", made with both technologies of aether and magitek. Can "deploy" in combat so it will almost be like piloting an armored mech. Offers high flexibility in stats, as well as abilities, which are tied to types of exo-armor used. This means you can combo your own abilities, to fill either tank or dps role. Can also choose to have a mechanical "companion" similar to summoner.
4. However, you can make the structure of the exo-armor look like, or be "inspired by", Eorzean beauty. E.g. animals, flowing design, all the good FF stuff. So in other words, you can achieve the "viera" look, tall, graceful, both animal-like yet humanoid, without having to bring along all its logical flaws. For instance, can even add antennas which look like rabbit ears. Flowing fiber-optics which look like hair. Strong mech limbs which look like muscled and athletic viera limbs. Or, can make it look like a fat, pudgy, tank ... or, a small, mechanical Klhoe-character, etc. If you add in possibilities such as stunted growth from things akin to the concept of "government experiments" which make them look young ... basically the Padjal concept, but dark and gritty. (I was thinking of Tio Plato, of Zero no Kiseki series when I wrote this). Also, why they can fit in the mech to begin with XD. But these are all just imaginative possibilities, for which there are infinite.
5. Tied in to be released with Botanical vault techs. (The Botanical Vaults design will be released by me in the latter half of September, or October, when I have time.) This is a separate personal project primarily to add more to the lore side of FFXIV. It's personal. ^_^ Depending on the heights I am able to work it to, it may even be worthy of being an expansion-level feature. (E.g. if I can truly make it representative of a core theme. Yes, that is why I can't just type that one out after a shower.)
