I was wondering around a zone and saw a cave and wondered inside to explore. Oh what do you know. Its Prince Arthas, duh. Hey he got a nice Libram at his side too. Be cool if we had one of those on armor.
Back in a earlier zone when doing a Quest the Lich King appeared. Oh Hi Boss! Man you are a Big Boss too. So what do I do, I screenshot it. He seem to appear in various places or taunt you in various ways.
