So after my runthrough with WOTP...I do agree that some changes need to be made. The culture production is much stronger than I realized until I really sat down and saw it go.
That said, I don't think a fundamental rethink is needed yet. Its true that the human can "milk" the belief more than the AI can...but I can say that about a lot of things in Civ 5. Its the simple fact that the policy gives such a large amount of culture for such a long time that makes it too good.
I think the simplest answer would be to put a cap on the maximum amount of culture you can get from a single conversion. That way it can still be really good (probably still the best faith -> culture converter), but a cap ensures the culture / faith ratio never gets out of control and that a human can't exploit the system and get 300 - 250 culture a spread.
