If Sorcerer started as a replacement for the Cult/Unseen’s 2nd player, and Inq started as BD that could help to balance the classes out better. Sorc would be easier to find, but Inq could potentially get converted (so he can’t just openly claim).
Another suggestion would be to simply buff sorc but having Inq be a convertible BD with her still being Neut.
Lastly, another potential Sorc buff would be to allow her to see or possibly chat with the unseen/cult so she doesn’t kill them and they don’t vote her up.
