I don't remember the exact number of wipes per boss, but Hans and Franz were...problematic. In fact, we still have issues with that fight, but slightly less horrific than before. Thogar took about two and a half nights of pulls to kill, but almost everybody got a hang of the trains fairly quickly towards the end.
