BING! Thats why in my book Vent is far superior to anything that comes with the MMOs themselves. The price is very small, I had a 10 person one I think it was like $11 for three months...IF I had wanted to split it between the 7 folks I gamed with, they would have laughed at me but, thats like .45 cents a month per person. Dirt cheap!
If it cuts down on bugs raring their nasty heads...just keep pushing the voice chat on down the line.
