Garlean Playable Race (?)

[Theodric]

They're boring and bring nothing new or exciting to the list of options, adding them as a playable race would be waste of time and resources.

That's completely subjective. A lot of people, myself included, have been asking for a tall and classically attractive playable race with no other features such as horns, scales or a tail for quite some time now. Garlean Purebloods if given a unique model true to their lore could provide that.

After all, the most popular playable races across multiple MMO's are generally either the equivalent of humans or some form of elf. That'd probably be the same case here in FFXIV if the proportions and design choices behind some of the character models were more palatable to mainstream tastes/conventional beauty standards.

As for it being a waste of time and resources? That's also subjective - personally I wouldn't agree with that. Nor would they necessarily need to be added right away.

The game's set to be supported for at least another ten years of development.
