The three Factions available in the game seem to be what balance in combat are fundamentally founded on, like rock-paper-scissors with a plethora of skill-based variables, but additional factions still seem to be the most abundant requests in the community due to many people wanting their or another culture represented in a Civ-like desire. The fact that the developers call the Factions three Warrior Legacies instead of races or cultures give the impression that it's the ideology and playstyle of the Factions that are meant to be embodied rather than race especially given this game's set in a world where these Warrior Legacies are not bound by region so anyone, regardless of race, could be conscripted, recruited or born into them, keeping with the realism and making the aspects believable. And even though almost everyone will be covered in armor, and rightfully so, bits of skin and the lower faces of Vikings are bare to reveal features that can be distinguished and help give a small, addition sense of embodiment. Just as there will be female warriors as abundant as male in this game's world, with tied-haired hanging out of helms and brandishing smaller builds, I think It'd be reasonable to have a small selection of varied human skin tones in warrior customization as well. I feel it'd be a beautiful answer to what people are actually asking for and emphasize, in addition to the female models, ultimately, that anyone can be a warrior, honor doesn't discriminate and what one values and what it contributes to their performance in battle is the only deciding factor.
