When I started playing Town of Salem, I wondered if the game’s roles would spoil me for normal games of Mafia/Werewolf. They certainly give me the wrong expectations. In a normal game, few to no players have special roles. The Town is working on little better than random chance until they see a few votes. The game is very different without investigative roles.
Hypothesis: most of the recent posts about leavers arose from people who did not like their roles. There is one great way to eliminate all those people up front: no one gets a special ability. Those players will not show up to that game to begin with.
I am increasingly speculating that leavers are cheesy one-trick ponies. He wanted a killing role. Doesn’t get it? Gone. And it needs to be one of the good killing roles, like a Serial Killer! Arsonist has to wait a while to kill — gone. Bodyguard must protect instead of actively killing — gone. Consort role-blocks — that could be okay, and it might become a killing role. (This undermines my premise of nearly random suicides.)
