As vampires and werewolves have gradually become more powerful, I think it would be neat to have a Fighter's Guild abilities or the Skilled Tracker passive have a buff to cause them harm. I'm thinking of this in more of a PvP aspect, because so many people are Werewolf or Vampire and there is little to no risk of doing so. If the Fighter's Guild had a more pronounced werewolf/vampire/undead hunter type buff, then it could create this risk for those who want to make a werewolf/vampire/undead hunter build (especially in PvP). Maybe instead of "This bonus doubles against player Vampires and Werewolves" it could be a quadruple or something like that? Just being imaginative with possible functional builds...
