As things stand now, I think the addition of more races would be counterproductive.

Many pieces of headgear don’t display on viera and hrothgar character models. Hrothgar hairstyles are extremely restricted—especially female hrothgar, who have five hairstyles per face, including two pairs of almost identical variants. Gear design has taken 10 steps backwards in the way it accounts for racial traits (or, nowadays, doesn’t account for racial traits), even for old races. Hats and helmets used to accommodate non-human ears with holes or pockets for those ears, but newer hats and helmets just remove non-human ears. And after many years of tails being left to clip through gear, we’re starting to get gear that simply removes them, which is even worse.

The races we already have aren’t being handled properly, with newer races having some of the most glaring issues. I’d like to see this trend reversed before we get any new races, at least, so those new races won’t come out horribly bungled.
