If someone finds it difficult to maintain balance, maybe they shouldn't create complex sets, especially for those players who sign up but don't contribute anything. Those who want to play will play even with a simpler set.
And since we're on this topic, maybe people shouldn't comment after the game? Just close it after the log, and then there won't be any comments about balance, evidence, and so on.
According to Arandor, it's "luck," but in my opinion, it's primarily the merit of the Stronghold player who identified and eliminated the mage on the very first night.
