Here's the Lady Deathwhisper feedback thread.

This is currently in very limited testing due to issues with the authentication servers and an instance crash on a few of the PTR servers, and this is being checked out right now.

There will be another opportunity to test this encounter.

Since these are the Public Test Realms, things do break on occasion. Issues discovered now are issues that should be fixed for live realms. The authentication/login issues affect my ability to login as much as yours, so I right now I can't login to help with access/door issues.

That being said, technicians are currently investigating the issue with login now.

We're also definitely going to schedule another test for this encounter.
