Category talk:Creatures found in the planes of existence

I have two questions about the subdivision of this category:
 * Should we make subdivisions like Category:Creatures found in the Great Wheel Planes, etc., like it was (so far incompletely?) done for Category:Locations by plane of existence, or should we keep it simple and just include one subcategory for each plane that comes up?
 * And now with Asuras I have an example of a creature that can be found in all the Upper planes. Should we do a Category:Creatures found in the Upper Planes (which in the future might also lead to Category:Creatures found in the Outer Planes, Category:Creatures found in the Planes of Law, etc.), or is that too complicated and should we instead just add categories for all the upper planes like Category:Creatures found in Elysium, etc.?
