These are the first few bosses that will be available in ICC. These videos are from PTRs so these videos are not exactly what the fights are going to be, but they will give us all a rough idea of what the fights will look like. If you go to http://www.mmo-champion.com you can find these same videos and a list of abilities and loot for each boss. The more of us that know what to expect going into these boss fights the smoother it will be. MUTE THE SECOND VIDEO and MAYBE THE THIRD TOO
