In Inquisitor games, by informing players that they are a heretic, it allows for extra confirmation.
2 BD will always be heretics. Meaning that a heretic claim is confirmed to be not starting Cultseen/NK/Neutral, allowing BD to track down the starting evils. The third heretic can be Cultseen, but generally its -EV to claim heretic anyways just because Inq can easily dispose of you by using a Sheriff/Pally claim or something.
I typically prefer Inq games because it makes finding evils a lot easier, to the extent that I believe it favors BD. Should heretics know of their heresy?
Another alternative I would like to see is a D0 message informing players that there is an Inquisitor in-game, instead of players knowing they are a heretic.
