>>20169678I think that based on the theory of genetic social hierarchy the meta/ethnic groups that are related to each other would share similar greater meta aka the memorised knowledge shared by the druid class. Having a social class of teachers that have knowledge of medicine, metal crafting, wood working, hunting and having them teach normies would have been incredibly efficient. One older druid can teach five and that five can teach hundreds of normies so that they can carry out their tasks. The druid class also worked as researchers that advanced the research tree so to speak. A group without this system would get wiped out if they faced a group with druids. Just imagine hunter gatherers going against horse riding milk drinking Europeans swinging bronze weapons! The personalisation of gods would have been based on the specialities of druids. Like metal working, weather forecasting, tracking constellations and warfare. This is why the MBTI, normies and noticers exist.
