This is the feedback thread for testing of the 10-player Normal version of the Feng encounter in Mogu'shan Vaults.
(Note: We are aware of issues with triggering Feng due to a problem with the mobs immediately before him. We are working on a hotfix to allow the boss to spawn.)
If you are unable to engage the boss, please try zoning out, resetting your instance, and trying again now. Thanks, and apologies for the inconvenience.
