Highmaul contains seven bosses, three of which are optional and two of which are mandatory. Players will take on Kargath Bladefist to kick off the raid experience, while the ultimate encounter leads players against Imperator Mar'gok, the pinnacle of ogre power in the region. You can also take the time to play around with the game's new Twitter hashtag campaign while you wait. That won't help you with the raid at all, really, but it will help pass the time.
In other WoW news, Blizzard will be kicking off its previously announced anniversary events today. Both the 40-man, level 100 version of Molten Core and the Southshore vs. Tarren Mill battleground will become available to players through the raid finder and battlemaster queue, respectively. Everyone who logs in will receive a molten corgi pet as a happy birthday present from the team. The events end January 6th.
