I think I'd go JOAT and Bus Driver, or just JOAT. I think we overrated Daychat by a lot and I don't think it's really worth taking actually.
Recruit or not recruit is an interesting question, but recruiting makes you so much more vulnerable to the Goon Cop that I wouldn't do it this time.
The JOAT+Bus Driver option is appealing precisely because it completely negates the Goon Cop (well, I don't know if they could both be assigned to the same player but I'm assuming they couldn't).
I'm thinking that Recruit is the least useful. The recruitee loses an ability, and you only gain knowledge of who the person is and ability to communicate with them. Of course knowing more is better, but in some cases it's an advantage to know less, because it's easier to appear like you're trying to figure stuff out. Plus as someone mentioned, it gives another Goon Cop target.
I wouldn't have seen the advantage in Daychat, either.
JOAT I don't like as much, because there's a lot of analysis paralysis on when and if to use them.
I've seen Rolecop used to good effect before in terms of fakeclaiming (Robz in Xmen and Ash in WoT), and Bus Driving is probably good with that. So I might choose those two. Perhaps JOAT as well.
Regarding the theory talk... despite what faust said from the mod perspective I didn't feel that it really did much of anything last time to help narrow down who was scum... mostly a red herring. But I guess something to talk about is nice?
I would not recruit nor get day talk. Rolecop becomes more useful the more roles you get (so I don't get why EgorK would say that) so I probably wouldn't take it either. I would probably take the JOAT and the bus Driver to make all players not guilty to the Goon Cop.
So first off, here are Teproc, WW and Yuma's responses to "what would you pick as scum" question. We already know that Yuma didn't do what he said here. Teproc explicitly mentions the Goon Cop which does give a little bit of credence to the idea that he is the Goon Cop. Obviously doesn't prove it but it's something.
What I was having a hard time with earlier was the fact that if Teproc is telling the truth, that means scum picked just recruit or just daychat (or we have more PRs in which case for god's sake say something), and I find it unbelievable that Yuma would do that. But then I realized that yuma could have been the recruited traitor on a team that was originally two newer players, something like WW and Ichi or WW and Andrew. And in retrospect, WW's answer looks very thought-out, a little like he's already discussed this with someone else. So did he recruit Yuma, then have Yuma explain in the scum QT that that was a bad idea? Possibly.
I keep going back and forth on this issue and I think I need to put it to rest. I keep telling myself that I can figure it out based on the setup but it's really going to have to come down to reads. But here's what I've come up with, and maybe it's helpful to the other players going over the thread.
