We still have the same amount of skill points per skill page even though new skills were added, so I could imagine getting that balance back with races offering an inherent epic skill each.
Let’s say there are 3 basic races. One could come with epic jump, another with light source, yet another with portal opening (just shooting examples from my unmentionable to give you an idea of what I mean).
I also like the idea of races having one of the atmospheric protections maxed out, or can imagine a race of hardened space travellers with warping distance maxed out.
Also one type armor or immunity at max level would be interesting.
Damn, with all I mentioned, it would lead to 10 races.
And I would really be happy enough to have 3 races to chose from now, purely as an esthetic choice.
PS. Mind that whatever a race offers skill-wise, would be active for all skill sets and alts.
