A concise list of the big shit that is bugging me:
Day 1, people start roleplaying as though they support the King, sort of missing the point of playing a werewolf game (ie the innocents are supposed to use the Day phase to find the werewolves and lynch them).
Ulric could have saved his life by PMing Forthwind at any point during Day 1, even before the bandwagon. It is normal for seers to contact the innocents that they find and begin a bloc; the only bloc that formed this game was one of faith (no pun intended) between Mormont and Althalos.
Ulric also seemed to value roleplaying more than actually playing.
Mormont revealed him/herself to be Friday. I have a lot of respect for Friday, but doing that goes against the spirit of an anonymous game. People should not be pressured into revealing themselves, overtly or otherwise. Besides that, the metagame of who's who shouldn't be anything more than a fun guessing game and should not affect play. I'm fairly certain it did in Friday's case.
This post here says "I am a wolf" louder than any post in the game:
I second Lyonel. I am a vanilla commoner.
Why in God's name does he say "I am a vanilla commoner"? Nobody else was claiming, and he claims the wolfiest role to claim because it's the hardest to counter.
The Guardians kept begging the Mad King to arrest them. I have no idea why. They wanted to look like high-profile innocents, I suppose, but first of all the Kingdom doesn't have a built-in seer ability and would therefore not know who the high-profile innocents might be, and also the only person who was arrested, Lyonel, was the center of suspicion.
Mormont could have spared Lyonel by using "cautious" mode last night, in case he wasn't a Guardian/hadn't been turned.
