Alright, so Dragonflight introduced us to revamped Gnolls. They’re obviously built off of the Worgen skeleton, which I’ll say looks surprisingly pretty good. I wouldn’t mind them being just a bit more chonky – I might have used the Tauren as the base skeleton (sized down, obviously) – but no complaints.
With the Kobolds, we’re obviously seeing a lot of new skeletons for them in the upcoming expansion. But monsters rarely have all the animations necessary for a fully playable Race. My natural inclination would be having a medium-sized Kobold built off of the Gnome skeleton (serving as a more comparable Alliance counterpart to the Horde’s Vulpera). I could really see the Gnome’s “waddle” sort of run animation looking good with the Kobold’s mouse-looking tails.
Of course, one or both of these should probably have a Horde counterpart as well. I’ve never been particularly fond of Quilboars, but you could certainly do that. I think a much more exciting option would be Ogres using the Kul Tiran skeletons as a base (though they’ve gotta keep their original Chris Farley dance animation).
I’d probably go a smidge more limited on their class choices – I don’t see either being good candidates for Death Knights, Demon Hunters, Paladins, or Priests (although a case could maybe be made for Kobold Priests with a belief based around their love of candles).
Again, just my two cents on the matter. While the Earthen aren’t the most exciting race in the world, it’s nice seeing the concept of allied races continue. I do think these might be a little more exciting, though!
