Also....the Acolyte background is available.
If you have the Acolyte background that means that you are an ordained priest even if you are not a Cleric, Druid, or Paladin by class.
So you can be an Acolyte Fighter which means you're a priest for SOMEBODY and who would that be?
Personally I'd also like to see expanded lists of available gods. Some of my favorites like The Red Knight and Sharess aren't there.
