Is the Lich King Encounter Fun

Firstly assuming you play the game to raid and enjoy relatively difficult content then you should enjoy the lich king encounter.

Featuring a normal and heroic mode, each with five phases; the fight is one of the most challenging available and lasts for 10-15 minutes, and is the only fight which features a cut scene at the end of it revealing a significant nugget of lore (Although you can now view this cut-scene in Dalaran anyway)
