Players have been reporting that their combat sounds seem to lag 30 seconds behind what is actually happening. I've noticed some of this myself every now and then, but what I find more annoying is that quite regularly a sound file seems to get stuck entirely.
THE absolute most annoying was when I had to do an entire Arathi Basin with the sound of the stupid Sen'Jin Fetish on the background. I tried taking other pets out, but it didn't work.
I was rather happy that the BG was finished and I could relog to get rid of the noise.
