Who is the most powerful nation and why?

[Twan]

EA... I answered Fomoria, not because I think it's the only best but because it's a good example of the strengths of a good nation in EA (good sacred, high hp units, extremely good national thugs). I could have said Niefelheim or Lanka instead (EA Atlantis has these qualities too, but can't be in the list because Oceania wins in the seas).

MA... I answered Arcocephale, not because I think it's the only best but because it's a good example of the strengths of the good nations in MA (cheap and powerful mages mastering one of the overpowered paths but also diversified ; some good units for early expansion). I could have said Pythium or C'tis instead.

LA... I answered Rl'yeh, because I think it's by far the most dangerous and a good example of the strengths of the two best nations in LA (freespawns, water access). Ermor is the number two.
