Then maybe they should have rethought the idiotic idea of having diplomacy as a
skill to begin with. I don't recall any other strategy game that did that; maybe there's a reason for that...
Which, btw, is a reason why the game can't work multiplayer. The fact that you have a +10 in diplomacy skill means jack to a human.
