Is there an incongruous distribution of magic?

Some of the nations get path combinations that are very rare outside of them.

E.g., EA Atlantis is one of the few that can pair Fire and Water magic. The only others I can think of are Jomon, EA TC, and Arco. Fire and Air has a similar very small list, which is more or less the above, minus Arco and Atlantis.

Earth/Blood is very rare as well, with Pangaea and IIRC Vanheim having the best access to it.
