Blood Legion of Illidan-US has scored the world first of 10-man The Fall of the Lich King (as well as The Frozen Throne.) Ten lucky Blood Legion members walk away with the Kingslayer title, and a... statue of Tirion Fordring? Well... okay. Why not? Congratulations, Blood Legion. Good luck on the hard modes next week!
Before everyone jumps to conclusions and bemoans WoW being easy mode, keep in mind this is only the normal mode of the 10-man difficulty. Blood Legion is a high end 25-man guild, so this kill was not what you would call "pure." A kill this quickly doesn't mean the encounter was trivial, because if that were the case we'd have seen many more kills last night. It simply means Blood Legion had an edge, to say the least.
