In WvW it is important to retreat for health when seriously injured. When a player leaves combat for more health the combat music fades almost immediately. The default WvW combat music is somewhat okay for this, but right now I’m using a customized music playlist and it is obvious when the music fades away after getting more health. I suggest making the music last for some seconds after combat ends. This way a player has a chance to return to combat before the music disappears.
