Bringing down Imperator Mar'gok is the most difficult boss battle in Blizzard's latest expansion to World of Warcraft, Warlords of Draenor. Only four guilds have been able to do it on the hardest difficulty. The one who did it the fastest is called Paragon.
Warlords of Draenor reviewed very well at Polygon, receiving a 9.5 on our 10-point scale. Blizzard says that the expansion has breathed new life into the franchise, with now more than 10 million subscribers. If you've been wondering, this video clearly shows what modern high-level WoW play is all about.
