Updated “The Boneyard Rules” added to the classes, particularly the priest. Priests have always been avoided in my games (mostly) and I am not sure if it was the sticky religion issues or that no one thought they were cool. Hopefully the abilities I gave them make them feel like 1) Priests and 2) bad asses.
Anyway, There are other classes out there but I feel that all of the others are sub-divisions of the main four. The distinguishing characteristics would be their skills. A Ranger is a fighting sort of chappy so he would be made using Warrior and taking a outdoors background or current woodland skills.
