You had a mole, though (albeit I know I was part of you learning about that) and you just said that Deo contacted the JL too, so the baddies did try and play the JL game then, and yet stood no change.
I do think that the setup was a bit unbalanced, and Wombat actually agreed in what ended up being a ghost chat with Wombat, Auden, and I. Among other things the purger and the sorc should have been the same player and there should have been four baddies per pack. There were only 29.6% baddies in the game. JHohho's rule of thumb says 33%, and with how the traits worked this game I think it perhaps should have been a tad higher, i.e. 10 instead of 9 baddies. In any case then three man strong packs are extremely fragile and always have been so. It's why they usually aren't adviced to make as they are very prone to falling apart fast.
When the baddies take out all major goodies in the first few nights and still don't stand a chance, then yes, things are unbalanced.
Just like how if the goodies lynch a baddie almost every day and still loses.
