Right, I forgot that in VP she always gets a religion... Kind of funny, in one of my games she founded 3 religions because her Holy City was conquered 2 times.That's a good strategy, actually. As she doesn't compete in the race of religion, she can take her time and prioritize other valuable things (units, Monuments, Settlers, Workers...). The ability to focus on infrastructure and still being guaranteed to get an (even optimal!) religion is her early game strength. If AI does these considerations... I don't know.
