okay, let me do some clean analysis. I'll assume that our two claims are conf!town for now.
These are 9 players left alive, consisting of
2 Vanilla Townies
1 Vigilante
1 Backup Vigilante
2 Mimes
1 Goon
QS the Watcher
Seprix the Neapolitan
Now let's analyze a massclaim. First, let's see how many lynches we have left. Right now it is
6/1/2
So, in order to have the majority, we need 4 town players left alive. That means we can lynch, no-kill, lynch, shoot (worst case). That makes 2 safe kills, 1 blockable kill.
Now let's assume everyone claims. Let's also not include our two confirmed towns to simplify things. Then we have
2 Vanilla Townies claiming VT
1 Vigilante claiming Vigilante
1 Backup Vigilante claiming Backup Vigilante
2 Mimes claiming ?
1 Goon claiming ?
That will leave us with an overlap of 3 spaced out over 3 categories. How useful that is depends on how they distribute their claims. I should probably stop here...
It does seem good to me though. Note also that, if the vig shot a mime, we have additional information
I think I'm in favor of a massclaim.
