Some nations have a veritable plethora of National Specific pretenders that you can only play through them. While making more pretenders for each nation would be fantastic, I would hope you could also limit a few of all these pretenders to specific nations (and of course try to allow nations to try to take advantage of blessings).

Maybe limit the Moloch to a few less nations? Along with a few others? Notables are Cyclops, Naga and Golden Naga.
