Also, there would be the grey area between PVP and PKing, which is always touchy ground. But if ever there was something to spice up WoD, it would be a clear and conscious decision to have PvP in the game.
I'm not particularly adept at monster-bashing, or even player-bashing (Admin-bashing, on the other hand, I have down pat
