4. I see Category:Content as the published stuff and their creators. Ideally, Andrea and the artists for The Last Tide should have their own page and be in that category with Pirateaba.
5 & 6 & 7. Agreed
8. I believe Category:Earther Technology should be in both Category:Equipment and Category:Earthers. It's a venn diagram of both.
9 & 10 & 11. Agreed
12. Maybe remove the subcategory that are in Category:Bandits from Category:Crime? Could stay the same since Category:Bandits is a subcategory of Category:Crime.
13 & 14. Agreed
15. Same as 8. It's a Venn Diagram. The Heartflame Set is both an Armor and an Artifact. Could be the same problem as 12, but perhaps some future non-enchanted armor will have their own page.
16 & 17. See 12.
18. Already rectified. Eye of Baleros doesn't have a subcategory, but it would be empty anyway, because we know nothing about them. I have a new suggestion instead. Rename that category to Category:Great Companies. Their number is not always Four in history so it's useful if TWI decide to talk about previous Great Companies like what is happening with Jungle Tails, a previous Great Company.
19. See my new suggestion 29.
20. See 10 since it's related.
21. Disagreed. Royalty and Nobility are both different things. Per the first two sentence on the Wikipedia page of Nobility: "Nobility is a social class found in many societies that have an aristocracy. It is normally ranked immediately below royalty."
22. Agreed
23. Liscor is an City-State. Liscor is an independent nation that is not ordered by any other people. The Walled Cities can suggest something, but Liscor is not forced to obey that suggestion as seen in the Election Arc where the Walled Cities backed Lism and in 7.23 LM where Liscor was threatening the Walled Cities. It's a city-state, because all the power is in the city despite the surrounding villages and farms that are included in Liscor's sphere of influence.
24. The other Hives got names: Armored Hive, Silent Hive, Flying Hive, etc, 7th Hive. They just don't have their own pages.
25. Category:Riverfarm should be a subcategory of Category:Unseen Empire. The land is the Unseen Empire is not just Riverfarm, but also the previous villages and cities that were around.
26. Agreed
27. Agreed, they are not needed.
28. I believe Category:Mounts should be a subcategory of Category:Vehicles. After all, a Mount is a living Vehicle and see 8
NEW 29. Unique Category that are Class with a Prefix and/or Suffix like those mentioned in 19 should not exist. It flood the category pages with useless data. Some characters would create a high numbers of categories by themselves. Bird would be part of Category:Bow-Singer Queen of the Free Antinium, Category:Bow-Queen of the Free Antinium, Category:Bow-Warden of the Songbird, Category:Queen of Freedom, Category:Antinium Queen, Category:Bird Hunter, Category:Amazing Liar. That's a total of 7. Category:Antinium Queens should stay since it's also a Subspecies + Title Category, but that's another question. For the Class Category, Bird, in my suggestion would only be part of Category:Hunter, Category:Tactician, Category:Singer, Category:Revelantor, Category:Liar Category:Warden, and Category:Queen. Other example of Class Category: Pisces should only be part of Category:Necromancer, Category:Mage, Category:Slave, and Category:Duelist.
