One of the most nostalgic things to me was the thunderous from dungeoneering. On release, all you would hear is him constantly saying "another kill for the thunderous!" because no one understood how to beat him.
Was a great way to demotivate players and make them feel like worthless garbage compared to a boss so I think this would be a great feature for when they make an uber hard boss.
