I know people have said that the extra kill was excessive, but I really think it was the only way to make the game fair in retrospect. The large amount of investigative and protective roles in play meant that with three town players basically confirmed we had no room to maneuver. There was very little path open to scum that way, we would be boxed in by DP3 completely. Just think if unsaid had used that role more wisely how completely unbalanced the game would be in town's favor.
Town lost for three reasons. The first is that they more or less ignored anticlaim despite a pretty dire and explicit warning. Can't really complain about anticlaim being severe when the OP underlined it in red ink for you and multiple people mentioned it and then proceeded to completely ignore it and claim DP1 anyway.
The second was relying on angleshooting. If Mikal had just used that info to craft his own PoE without mentioning its source there would have been no mod reprisal and scum would have had more room to maneuver, as the advantage conferred would be small. As it stood the consensus was that we either needed to reroll the entire game or give scum a severe offset to counteract almost half of town being confirmed that way. Most mods don't want to reroll a game, so I feel like eventually angleshooting will be seen as anti-town behavior because mods will respond to it aggressively to rebalance the game.
The third was unsaid just yoloing it, wasting a powerful role, and killing himself in the process. As Whiteflame already said, it makes zero sense to use that role DP1. If he had just waived that role could have changed the game NP2 by counterbalancing the NK.
