Okay, question for everyone. I have an idea, but I'm not sure if it's a good one...
With this many players, the investigators have a lot of guesses, and plenty of chances for the witness to hide behind someone. In the interest of giving the criminal team a bit more of a fighting chance, I was thinking of trying this rule, which I couldn't pull off in a tabletop setting;
Instead of rolling the dice and assigning the roles of murderer and accomplice to individual players, I'd instead roll 2 players that would be the Criminal Team. They'd get the same group PM along with the FS, but instead of me naming the murderer and asking them to pick, the criminal team would decide which of the two of them would get to be the murderer and the accomplice. The murderer would still pick only from their own set of cards and gameplay would continue from there as normal, it would basically just give the evil team a little bit more options during the setup.
As always, the witness would learn that those two individuals were seen at the crime scene, but since they never learned who was the murderer and who was accomplice anyway, it wouldn't have any impact on their role either.
Anyway, what do you guys think? Try the criminal team rule, or stick to passing out specific roles?
