IIRC, i lowered the threshold by a point or two, and i no longer know if it's still possible to get a 'perfect hand' of everybody staying + everybody else available as exiles. part of this was because there's actually more content for exiling characters than having them stay in the village, since raven and max also have their own exile recruitment sidequests, whereas generally once somebody stays they just kind of vanish from the game. plus a bunch of people complained about it being very difficult to 'win' at all.
(the ideal solution would just be to add in more village content for all the characters, but, well, that's a lot of content.)
