JoeSapphire: Doesn't the even-number-of-players-means-an-eventual-no-lunch rule only work in a game without power roles?
Or is it a different rule?
No. You can have power roles as long as they don't affect parity. i.e. they don't affect 1-lynch-1-NK cycle. So you can have Cops, Trackers... etc and it would still be right to vote NL if the number is even.
In a closed setup like this, where you don't know what roles are there, it's very bad.
my name is supyreor catte: And yes, I think in the strictest sense it's only definitely the right thing to do in a game with no PRs.
You of all people should know though that a "false positive" NL mistake is much worse than false negative. i.e. lynching someone when the correct play is NL only decreases town EV slightly. On the other hand, NLing when the correct play is to lynch someone greatly decreases EV.
