Wow, you mean their not the powerhouse I thought they were.
I really am behind on the times. What patch(s) were they nerfed in?
I still think they are fun to play. Since the AI caps surround this player the dominion effects will mostly be on the AI which players should be fine with. And effective preaching/strong dominion should deal with most of it. While I find their dominion annoying sometimes, do you think it as devastating as LA Ermor's pop kill dominion? LA Atlantis is a possibility in the role but would require at least one land province in the center of that sea (have to check the sea/land cap resource gathering thing).
