Here is a great video of a group of players doing the 25 man ruby sanctum run in the world of warcraft cataclysm beta. The video is decent quality and lasts for over five minutes so you have plenty to enjoy. I’m going to say that this might be the expansion that gives players another reason to jump back into world of warcraft if they left. Not only is the games 1-60 being completely changed, but the game is going to have an amazing new addition of end game bosses and quests. Well anyways enjoy the video.
