I think by far the worst I've ever encountered was the traditional keeper clan groups. Conceptually, my interpretation of the keeper clans were that they were Wacco or Onion Town (look it up) sovereign citizens who formed small communes outside of Gridania, hence why they would be described as more solitary or independent, who hunt for survival. But for some reason that is completely unknown to me, you'll get these fucking clans that will practice dark arts (which would make them enemies of the state), worship alleged primals or eikons, or they'll have primal clan politics that would make south american and african tribes blush in comparison. There hasn't even been a single mention of keeper clans exhibiting this behavior at all anywhere in the game and even if we were to handwave that, the clans would be so small that any kind of politics would never grow beyond just ground rules and distribution. These are small families living sovereign outside of city limits kind of like those backwoods rednecks, not tribals worshipping false gods.
