Fortunately this is rare, but occasionally you get bored/ bloodthirsty players leading particular cabals (in this case the Battle Ragers), and exploiting imbalance is usually exactly their reason for declaring War in the first place (because they have deathblow, resist, spellbane etc everywhere, whereas Tribunal has nothing outside the cities). So there's no balance, but it's not something that should be/ needs to be balanced for anyway. I imagine IC-ly the relevant cabal imms would deal with it eventually, and in the meantime the Tribunal players are not helpless either, can get creative with solutions.
