This issue isn't specific to Isle of Conquest, but it is where it became most obvious. Even when I am standing by myself in the keep, at the quarry, or wherever, I can hear all battle sounds and fighting as if they were in extremely close proximity. It's a little overwhelming. I keep turning around expecting to see a fight but no one is there.

At this moment my character is in Dalaran, with very little going on around her, but I'm hearing dozens of sounds with no known origin. Sound does not seem to dissipate over distance before it reaches my ears. Even if it is 100 yards away it sounds loud enough to be happening right next to me.
