Okay look
What basically happened is the powerful BD roles got swapped from Prince and Paladin/Sheriff to Prince and Priest.
For that reason, it’s okay for the Priest to be powerful. As long as balance is maintained with two BD “Power” roles in play (somebody come up with a better name for this), Priest should be able to be powerful.
The issue right now is that there is literally zero counterplay to the Priest. This is somewhat expected with the Prince - evil jailor is broken, plain and simple, so conversion is off the table, and although it should probably be able to be occupied it isn’t a huge deal that it isn’t because it’s always worth using a kill on it, even as Cult where that kill comes with a price tag. But the Priest has the same issues the old Paladin did - it’s an unstoppable God amongst puny men. The current Priest has only one weakness, and that is occupation. But if he just revives N2, that pretty much no longer matters. If there was some way to counter his ability, it’d be fine. But there just isn’t.
What the Priest needs is counter-play, of some sort. Losing conversion immunity post-revive is a great solution that ensures that the game can be balanced for 1 BR revive, but reduces the cheese effect that two more conversion-immune classes has of the rest of the game. Removing the night immunity grant Priest has also allows that ability to be given to another, future role instead.
And while I can see where the night 1-3 immunity argument comes from, I think that we should wait and see if the other changes I talked about are enough first. ToL gets updated enough where it shouldn’t be a huge issue to take this one step at a time, and evaluate it needing timed night immunity later. After all, it should have different weaknesses than the Prince.
