Asdioh, like I said, I'm not super salty about it. The set-up is just swingy, and it swung very hard in scum's favor. I don't mind swing at all; I think it's fine. Ryker exploited his ability very well, and town did not play well at all. None of us. Where I take issue with what you're saying is mainly in the idea that town were overpowered (no way), and that certain things should have seemed fishy to us that we didn't catch. I think you've got mod-goggles on there.
It did occur to me that Ryker should be dead if he were town all this time, but there was always a pretty easy way to excuse it "scum wanted to kill the Cleric and Ryker's used up his shot," "There's still a cop in the game; scum wanted to try to hit the cop and Ryker's definitely not it."
And you say we should have suspected something was up when Zen flipped Cleric. Or when we noticed multiple "town" killing roles. Why? Zen's flip only means that there would likely be a mafioso with status ailment flavor, not that Ryker is that mafioso. Should we be wary of vig claims when we know a doctor or jailer is in the game? Of course not. And yes, according to the claims at face value, town would have had to have quite a few killing roles for a game this size. But that's still much less weird than the freaking mafia having a second killing ability, period. Like I said, I didn't entertain the thought of that being a gambit because not only is that a crazy gambit, it is also a gambit that I wouldn't even expect the scum to have the option of doing.
Plus, the Sucker Puncher is basically just a PGO, and the Executioner just made a lynch easier, so in terms of raw killing power, having one town vig in this set-up wouldn't have unbalanced the numbers much. Especially since, as I mentioned before, the Executioner's ability can be used against town, as would a hypothetical town vig. The fact of the matter is that the poison ability—though it could fail on certain players or be blocked by the Cleric—was a free, guiltless-looking kill for the mafia, separate from the normal NK. There's no getting around it. That's powerful, especially in a small game.
It was completely sensible to clear Ryker for what he did. I would have considered it sensible to clear Ryker even if he had killed a townie. I would just never expect scum to be given extra killing power like that. As far as I'm concerned, the only way we would have caught Ryker is if he got Cop'd, and our Cop was handicapped as it was. Like, I said, it's really just a matter of swing; town could have gotten lucky with the PRs and wrecked scum. That's just not what happened.
And of course it doesn't help when so many players are inactive or playing safe. It was so easy to just slap a scum label on Vocal and call it a Day. Oh, and let's not forget that the one modkill of the game was a townie. Technically, it was just the difference between mylo and lylo, but still. A revolving door of inactive townies along with a couple who basically just decided to stop playing wholesale made it difficult to get a strong bead on a lot of players, I feel. The only really strong read I had was my town one on Ryker, and that was entirely due to the gambit.
