I like this setup a lot. Simple yet effective. Of the four possibilities I think we got the one that was the worst for the mafia, but that's the luck of the draw. Could have easily got a setup where there was no town power roles.
I think the biggest mistake I made was not turning on Lance sooner. I should have voted him before I left work at the end of day 2. Then Psy conceivably would have forced a tie with a Levian vote and I may have been able to turn it around and get Levian out.
