I have had a few games where i ended up being Prince or King, and was too tired, and too overwhelmed to actually play the roles as needed. Missing key information, or going against agreed tactics, because i did not have the energy to pay the needed attention to the chat going on. I have on a few occasions ended up making it a loss for my faction.
So i kinda miss an option to prevent me from being an important decision maker when i feel i am too tired, but still want to play. In my opinion, it should only relate to King and Prince, since other key roles still are less stressful. You can still be a good MM while being tired, and you can still be a good Neutral Killer as well.
Just throwing my idea out there. Maybe make it a feature under the account management, or in the game settings.
