NPC Health Bars/Nameplates are now appearing correctly.
Thank god.
This was painful when tanking to know whether all mobs (or any!) where still hitting you.

I wish they did something about the sound. When i go into an instance or group, my sound literally lags a couple minutes.
That is, we kill the boss and exit the instance, and a minute later i get all the sound of the fight, even though i'm just flying somewhere or whatever,
