The Seer is not a reward
I would never try to become a Seer. It's a death warrant:
If you are a Faithful, and pick a Traitor, it's obvious one is lying, so better to get rid of both to be safe
If you are a Faithful, and pick a Faithful, they may think you are both Traitors, so same result.
Traitor picks Traitor? Same result as F+F.
Traitor picks Faithful and lies? Same result as F+T and dangerous for T. Tells the truth? Same as F+F.
