If you could get rid of one playable race and replace it, what would you choose?

[Jeykama]

I'd get rid of all the color-swap race "variants" and replace them with physiological variants (e.g. midlander/highlander). There could be humanlike moonseeker/sunseeker template Mi'qote and more bestial Mi'qote. Tall normal Elezen and petite Elezen. Normal Roegadyn and stone-like Roegadyn. Normal Lalafell and Lalafell that don't hide their demonic core.
