Knights of Tezoth

In general, this is not a question of imbalance, and certainly not of "sudden rules" (because no rules were actually introduced), but rather of tactics and the desire to "let the NPCs suffer just so that one of the players wins."

NPCs should suffer, at any cost. After all, in most expeditions and in most cases, it's the player characters who suffer. Even if they're super lucky like Heroist's character in Izkazan. Compared to Hatarait, he still sucks.
