Do you mean what? Models and textures? If that's the case, there are plenty of models in the game already, they already cover all cultures in game, including acheronian and atlantean and even darfari (maybe not aesir), and many professions - scholar, priest, merchant, citzen, beggar, etc. So it's not a matter of making new models, just a matter of choosing better among the existent ones. Seems Funcom didn't gave this much attention, unfortunately.
But to be honest most lvl 80 people I see running around use vanity to look like a weirdo, naked, hyborian version of Jason Voorhees, especially in Khitai. I don't think they care.
