With the latest patch release, we’ve added two new arenas: the Dalaran Sewers and the Ring of Valor in Orgrimmar. These arenas offer new obstacles and challenges for strategy savvy players. The arenas have been added to the random rotation and are accessible via the queue system as Skirmishes. For more information on these two new arenas, please visit http://www.worldofwa...er/11/arena.xml . Both Dalaran Sewers and the Ring of Valor will also be available for tournament play during Arena Season 5.
We got word from Nethera and it looks like the two new arenas, Dalaran Sewers and the Ring of Valor, are officially in the Skirmish Arena rotation. So, if you're curious, go give them a whirl.
