To answer your questions, I'm more just trying to analyze the pieces of information we have from every angle so I can place it into my logs and speculation. So far while playing, I haven't seen a role like what Alca appears to have, so naturally I wanted to parse and analyze it for myself and see where it led. In the end, I commented that I saw nothing in her apparent self-initiated death to be beneficial to a mafia role and that I read it as her being town.
I do feel sorry for Alca that this is the second game in a row in which she gets a suicide role, though. ;;
I'd still ask for clarification on the reverse-miller to make sure I understand you, but I also think I'm confusing myself with how the X*/Y* works. Would it appear in rollover as... for an example, base ratio is 7:3. Someone dies and turns up without alignment information (which suggests they got hit by a janitor?). In this case, the ratio would appear 7*:3*? And then if someone dies after that and they're definitively mafia or town, it would read 7*:2* or 6*:3*, respectively?
But in the case of a miller, the rules state that the ratio would continue as if that player were the alignment they flipped with. So in Kotakia's example (using 7:3 again), if it were a town milled to be mafia that died they'd show up as mafia and the rollover would read a ratio of 7:2, correct? So then they can exist in the game, as per the rules?
Also, I'd really like to hear some input from other players, too.
Edit: Got ninja'd by Kotakia while I sat here figuring it out, rip me.
