I witnessed one of the killer wins. I quite like the setup anyway. It's better than the other comp setups which is sheep the tracker and such like. This is something different and fun to play.
I can understand why the maf has such a low win rate, it's because the Killer has a habit of killing off mafia. If it's on the very first day, the other mafia might as well just surrender, because they can't win.
Love it.
