Anglican is OP
I want to mention something about Anglican and why it is very good in my opinion.
I am currently in my Great Britain run and switched to Anglican to try the religion and I really like it. You can get so many ducats to improve you trade and economy in general. You also will remain defender of the fait and will never get called into stupid wars, because Russia attacks Anhalt.
True it doesn't give you all the catholic bonuses you can get from the pope, but extra 1k ducats every 6 months is a very big advantage of Anglican
