Tomb of Sargeras is now open for testing Raid Finder difficulty. Specifically, the second wing (Wailing Halls) is now available on the PTR. We expect to keep the wing open for the entire weekend.

Please use this thread for feedback and bug reports regarding the second wing encounters, or related issues. Noting the nature of your group (Mythic guild premade, PUG, etc.) is helpful, as are any logs.

Thank you to everyone helps test!
