Three words: Centaurs and Nymphs.

We've got all these creatures in the lore that we've seen, but these two have been just left and forgotten as if they have no place on Nirn. Now obviously, Nymphs are a little more...far-fetched to add in the game, since there's really no lore for them, except them showing up as "monsters" in Daggerfall (the game not the city), but Centaurs have a place, and they've got an established foothold in the world. Elder Scrolls Legends has them as a card that explains that they're found in Valenwood, and in High Rock. So hows about we get to seeing them (or one) here?
It's a pipe dream, I know.
