I'm not relying on that but looking at notty's "Possible outcomes" none of them show Rev killing mafia, doctor saving someone, toxicologist saving someone, mafia being blocked, rev and mafia targetting the same person.
All these possible variables completely throw a spanner into this grand guesstimate notty keeps spouting because as you really should know, it is impossible to predict mafia games.
Dictator kills result in us not knowing the alignment of the victim so we could be shooting ourselves in the foot without realising thus as town we can't adapt as I have said ebfore.
Likewise doctor doesn't know who the dictator is the night they're elected, neither does bus meaning they're at full risk of dying every night. The only certain way we could catch the rev with the dictator route would be to put the watcher in the council so they know who the dictator is and they can see who targeted them upon death.
Democracy is harder and relies on us making better choices and putting in 110% to catch mafia, but autocracy is riskier and is less in our hands due to the ambiguity of it.
You have to remember mafia have more information than us regarding who's who, so why take away even more information from town?
