One reason that most people do 1 warrior and 1 priest is because the priest game is so separate from the rest of the game that one can often become heavily detached from the actions of the realm. It is much closer to the adventurer game than the noble game which is why so many people begged you to treat priests as adventurers. When I had a single priest in one realm with no one else, I literally lost track of the realm. When I brought in a warrior to the realm it helped to anchor me to realm and made me a much better player in support of the realm.
