The kill is filmed from the perspective of a DK, though, frost DPS Cize, and shows the entire kill from start to eventual finish. What's surprising is that they don't seem to hit the apparent enrage timer, with the fight lasting 14 minutes and 27 seconds. Their team was Cize, ilvl 576, as well as Lyzian, a prot paladin (572), Vayce, a discipline priest (575), Vranis, a fire mage (569) and Depression, a combat rogue (573). The armory is having some issues which are preventing me from seeing the characters today.
The kill took them 30 attempts, and the logs can be found on World of Logs.
