Not sure if this has been said before since I tried searching for a similar thread but to no avail.

I understand the appearance difference between clans, but I hope to see characteristics that are shared.

For example, keepers of the moon and seekers of the sun.
  • Suns have slit eyes.
  • Moons have fangs and long tails.
So, to keep a clans' uniqueness, just make the skin tones exclusive.

I just like the option to have a long tail, a set of fangs, and a pair of slit eyes for my male Miqo'te when 2.0 rolls around. And I'm sure each race will have newer characteristics since Yoshi mentioned more customization.

TL;DR - Let races share characteristics but keep their clans' uniqueness.
