There have been two threads discussing the problems with piety, and I agree. With some small modifications piety could be improved.
I propose the following piety tree:
Opener: build shrines in half the time, shrines provides +1 faith
Almost guarantees a pantheon, what you need early
Organized religion: build temples in half the time, temples provides +1 faith, temples increase the gold output of a city by 10%
Makes temples decent, bygathering all the bonii in the same policy. Good if you make a temple/shrine religon.
Righteousness: the cost of purchasing religous units and buildings with is decreased by 20 %
no change except the name which did not fit
Reformation: (requires Righteousness and Organized Religion)
no change except the required policies
The Holy Land: Holy sites provides a combat bonus of 15% to units of their civilisation in adjacent tiles. Holy sites give + 3 gold +3 culture.
The same as temples, collect the bonuses in one policy. Holy sites may actually be worthwhile with this policy
Religous Tolerance: Cities benefits from pantheon beliefs. 4 Global happiness.
Piety needs some happiness and religous tolerance is generally not so useful, though occasionally brilliant (say if someone took desert faith from you)
Finisher: Free Great prophet, does not count towards your great prophet counter.
The problem with great prophets is that the cost increase so rapidly that a free great prophet is a small bonus
