Well our intention with this project has always been to create a feeling of variation for all cultures and all that, for example me and Myrddraal once discussed how to design the diplomats, and all cultures will not have the same with different skins. Aiel will have wise ones, aes sedai and aes sedai and the visiual apperance of the others will differ more then in just colors. The same mightbe done with armies too, with different nations having their armor.... that is, if Myrddraal hasn't changed the idea since we decided that.
