Inquisitor seems too Blue Dragon friendly. He may as well be one, since Sorcerer sides with Unseen/Cult. Blue Dragon wins most games anyways, and Inquisitor doesn’t even need them to win. Just the NK to lose.
So what if the Inquisitor’s goal was to kill all starting magic users (not non magic converted cult). It would make the class more hostile to the Blue Dragon, while still working as a counter the Sorcerer. I think this would make it a class you’d have to work to win as, instead of being nearly guaranteed the victory.
