More lithe builds for the men and more muscular builds for the women would be lovely.

I would also absolutely love it if you could choose some basic personalities. Maybe someone would like to play a Miqo'te who's shy and reserved, or refined and seductive instead of everyone having the same excitable girly-girl emotes that every other Miqo'te have. I've no hope of this ever being truly implemented, but it would be so nice to be sitting around with a group of Miqo'tes and not have to cringe when I notice they're all sitting in the exact same way. It's just one more thing that makes us seem like exact carbon copies of each other.
