In game voice chat is a great feature to this game, but it is annoying when some people's mics are really loud and some are really soft. A great customization would be the ability to increase or lower the volume of each individuals voice volumes within their party/raid. A good example is Ventrilo voice chat which has a special feature when you go to miscellanous and special features. You can edit each individual's voice volume and it will save automatically for each time that person is logged in. I think this feature would be a great addition to voice chat.
