Why do you think the setup messed it up?
For instance.
You kept saying the game had follow the cop, that the PT Cop was a threat.
Because the false guilties were removed, thus, all future guilties would be real?
What you fail to think about is that is an incredibly scum-biased viewpoint;
the town doesn't know all future guilties are real
.
zMuffinMan could have claimed he had a commune/mysticism/some seer flavored PT; this would be a simple alteration to his existing claim and would fit completely and entirely in the setup.
Titus could have claimed she had a Detective's Notes PT; this would be a simple alteration to her existing claim and would fit completely and entirely within the setup.
Toranaga if opting to go with the Devourer safeclaim as he did could have claimed he had a Devourer PT, which given the mafia PT would be a perfect fit for existing within the setup.
You, as a member of the lynch mob, were already given a cover story and could thus not be guiltied.
Then there's how the vampire removing PT access can lead to a false innocent.
Then there's how traitor speculation can and did happen, calling results into question.
Then there's how the PT Cop made sense as a scum role flavor-wise and this did contribute to the hebichan lynch.
Then there's how the vampire could have permanently become a false guilty, by successfully draining EITHER the jailkeeper OR the neighborizer. (While the vampire's target for the jailkeeper PT would lose access after the day, the vampire would retain access indefinitely). So the vampire had the potential to become a false guilty, a potential you didn't know of but I as the moderator was quite aware of.
Then there's how the jailkeeper, neighborizer, lynch mob, and mafia were all false guilties.
The neighborizer recruiting creates another false guilty on top of that.
The lynch mob recruiting creates another false guilty on top of
that
.
Plus, if the neighborizer/lynch mob recruits scum, then said scum now has plausible deniability for why they have a PT. Keep in mind, with one scum starting with a PT and two PT methods,
three scum could have become immune to the PT Cop N1
. If you had THREE scum immune to the PT cop on N1, how would that, in any way, even remotely, allow for a follow-the-cop?
This isn't even remotely a complete list of the reasons there wasn't follow-the-cop in play, but it gives you an idea of why it wasn't there.
Because of the mafia naytheist with a mafia traitor?
The mafia traitor did not, I repeat, did NOT make the naytheist a mason to flip.
Given this setup was explicitly, "Red Herring: The Setup", I can and would include a backup to a nonexistent role; I can and would duplicate kill flavors. You raised this argument to lynch Nosferatu, and while the town laughed at you for it, you were not wrong to have argued it because I can, have, and WOULD pull a stunt like that.
Furthermore, while you couldn't kill the mafia naytheist, true enough, this was counterbalanced by the mafia naytheist holding the power to royally fuck the town over--his kill could puncture through doctor protection, and he almost killed hebichan at least two if not three times; any of those times would have meant no guilty on Titus and if earlier, no innocent on Vecna.
The mafia naytheist was, as Jingle so aptly described it: a "NK-Immune Miller Vig". The town could, very reasonably, conclude he was a serial killer from that, and lynch him due to the role screaming SK. (Which was the design intention.) The town could, very reasonably, conclude that MAFIA are enemies, because of how they're...y'know. MAFIATES.
For that matter, the mafia could--and to a limited extent, DID--think themselves to be those things, serial killer/anti-town, unable to win with the town, and trying to play as if one, making deliberately anti-town shots.
In other words, the mafia naytheist was designed so that PLAY would determine its utility, beit positive or negative. How the naytheist perceived themselves, and how the town perceived the naytheist. Nosferatu ended up correctly perceiving himself to be town; the town ended up correctly perceiving him to be town. But there was a HIGH potential for them to not do so--do you honestly think that ten towns out of ten towns view Nosferatu as town? Do you honestly think a hundred players out of a hundred players receiving Nosferatu's role assume they are town?
I mean the numbers might not be an exactly split 50/50 distribution, but they sure aren't 100% in that viewpoint, or even remotely close. I'd estimate that it'd be around 60% or so for them to come to the correct conclusion, if they know moderator meta; if they don't, the odds plummet down to 40%.
