Siege of Orgrimmar
Cross-Realm raid browser (located in the Social Pane under Other Raids on the Raid tab) now has a minimum item level requirement for players attempting to list for Siege of Orgrimmar on Flexible raid difficulty.
Vale of Eternal Sorrows requires a minimum item level of 510.
Gates of Retribution requires a minimum item level of 517.
The Underhold requires a minimum item level of 524.
Downfall requires a minimum item level of 531.
I'm sorry, but you are incorrect. The real iLevel requirement for flex SoO is 540. Please update the patch notes to better reflect reality.
