The Ruins of Ahn'Qiraj will be released on the 5th of May. There was a month delay because of requests for a more stable release which is why we will release the entire raid in one go. It will start off with our maximum buff (same as BWL) for those seeking a challenge, it will obviously be reduced if that turns out to be too much for 20 man.
On the other hand, the buff for BWL will be reduced. It will not yet be as low as the other raids but it will be more accessible for smaller or less geared groups.
In addition, all Vanilla quests have been enabled
except for the ones related to Naxxramas.
