Tired of complicated timing and precision-based fights, Blizzard has decided to go for the jugular and let dungeon bosses attack on a more emotional level. This particular boss, the Judgmental Father, is found in Uldum and is very disappointed in you.
He worked himself to the bone for 30 years just to give you a better life, and you spend it sitting around eating Doritos and playing this stupid game. The Judgmental Father is expected to have a devastating effect on players with unresolved emotional baggage. (Thanks to Elliste of Lost Isles beta server.)
