For people wanting to see Undead and Gnome Paladins, here is why having Priest for a race does not guarantee having Paladin. Priests bind light and darkness within a psychic/mental context and NOT necessarily through faith and zeal towards an ideal like a Paladin does. For example, Forsaken Priests usually grasp the Shadow and figure out the counter-balance as a means of knowing both sides of the coin. Being a Paladin means that one is entirely devoted to holiness rather than the Light in general, therefore bearing the traits of the Light as a creed, instead of an "element" of its own.
In other words, Priests get attuned to their domains and they may not be a zealous avatars of their creed like Paladins are. However, I would like to see a darker side of Paladins, especially one applied to the Forsaken. One of my greatest RP fantasies is to see the Forsaken treat crusaders the same way that they themselves were treated...by judging and smiting crusaders.
