Starting w/High Dominion vs. Using Temples

[Ynglaur]

Is there any point to starting with a high dominion, assuming that over a long game you can build enough temples to get the +1 Max Dominion per 5 Temples bonus? I understand the benefit to an early dominion push, etc. but assuming a large map, and the ability to throw up 45 temples before a serious dominion war, or perhaps using priests to hold off an enemy dominion push until temples are built, is there any long-term advantage to starting with higher dominion?
