If they go the realistic route they should make the female armor the same as the male armor. Of all the pictures I have seen from medieval times depicting females in armor, they wear the same as the males did, as that was the most practical and cost-effective way to do it. Though personally I would go for something more aesthetically pleasing, if it isn't 100% realistic or practical I don't really care, it is a video game after all if it had been a LARP or something like it then yeah, realism should be the norm, and no this don't mean they should go as far as TERA Online did with their armor, but a good variety of styles ranging from practical to aesthetically pleasing
