This is guidance video.
The instance name is ˇ°Icecrown Citadelˇ±. It is a new raid. And I will mainly focus on the first four bosses -- Lord Marrowgar, Lady Deathwhisper, Gunship Battle and Deathbringer Saurfang.

It is normal raid (10 players)
They are Death Knight, two Paladins, Hunter, Rogue, Warrior, Warlock, Priest, Mage and Druid. The ten players will complete the raid. I (Rogue) am a leader.
