I'm totally with mr. Gandalf for a large random map with many chokepoints
VP in role we could talk about them like important points from which pass the vectors of the world (a lĂ* Black Tower of Stephen King) which the people somehow know (or have a confused idea) they must control in order to leth their god ascend. If someone could also mod the VP to be also "many sites" provinces it would be perfect IMHO
