Group (Ethnic) vs Race/Species Topics

[kate]

The Story/World almanacs have a topic type called "Group (Ethnic)" which the Tips & Tricks manual says is suitable for elves, dwarves, and the like.

However, the mechanics section has a topic for Race/Species which presumably is also suitable for elves, dwarves, and the like.

How should we / how do you use these? Pick one of the two and stick with it? Use the Race/Species entry for basic elf & dwarf info and use Group (Ethnic) for subgroups like "Sylvan elves" vs "High elves"? Put mechanical info in a Race/Species topic and flavour in a Group (Ethnic) topic? I could see the last one complicating linking since there would be for example two topics named "Elves."

I've currently got my flavour and mechanical info mixed together in "Race" custom category pages I made before either of these categories were introduced and I'm trying to figure out how to convert it to the base framework.
