With the release of Patch 5.4: Siege of Orgrimmar, four wings of an expansive new raid will begin to open. The Normal and Heroic raid difficulties, Raid Finder wings, and the new-to-5.4 Flexible mode wings will each be available starting from different dates.
To access the new Raid Finder wings, you’ll need a minimum average Item Level (ilvl) of 496 or higher.
This is our current schedule based on the planned patch release date of September 10. If we determine any changes are needed, we’ll update this article.
