Well, unless players want to bring forth some new information, I'm not certain there's enough going on at the moment to figure out if someone is Mafia, other than the fact ChopBam and iLTS have OP enough abilities that it's unlikely they're Town.
I'm assuming it would be directed at stopping Mojoman from using his hammer if anything if it's a Town ability. Which now would be a good time to use said ability if you had it.
What do you think it would be? There's a limited number of abilities that would actively announce they've been activated at day start unless it was a warning of some sort.
Who knows, as far as game balance is concerned, we have two players that can replicate the best abilities in the entire game, and everyone else only gets their own two actions?
