Drunk sort of complicates things for both sides. In the cop CC, someone claiming roleblocked can be either confirmed or denied by the PR. This means the mafia has to be ready to double CC (which sets teams, meaning if you lose the CC as mafia you lose the entire match).

Also might make it a bit townsided because a drunk alive on d2 can create a clear the next day by declaring who they're going to roleblock.
