On the subject...

It may come down to their habitation ... habits. I'd find it odd if they precisely mirrored the Viera in their lifestyles, but perhaps the males live in separate villages in their case, some of which were wiped out by the sin eaters... total eradication would be a salient point for an NPC to bring up, but it was not, leading me to think it's not the case. They don't refer to themselves as doomed, so there must be something else going on. Either way, I really enjoyed the foray to their village.

Also agreed on Urianger's build being good. Iron out all the kinks in Elezen, give a muscle tone slider, and you have a decent basis for male Viera.
