Have fun having no one die on the first night, then
*Cough*
No, the reason why it should be and was a thing is because of issues of optimal play, people being inactive, and the one person who was doing anything not horribly dying on the first night, watching everything he set up crash and burn. At the risk of sounding like an arrogant twat, I had to badger the mafia from the grave - borderline breaking the rules about not talking - to get nightkills done. Not trying to offend my fwiends on the mafia side, but that's how it was.
Not to mention that every other mafia I've been mafia, this was completely fine. It's really the (apparent) sudden change of rules that's causing this.
Maybe I should just hate on roles that care about which mafia member sends in the kill instead; then this wouldn't even be an issue.
