Mics on the Xbox?? Never used it at all. I am using vent or TS a lot in WoW or other PC games but on the xbox I prefer to play games "alone". Sometimes with a few friends but never in the online mode.
I can´t stand the guys on vent in Wow either All those jerks in random raids and stuff.
BTW: Yeah I mostly play racing games on the xbox so I don´t need a Mic I am still playing Forza 4 and Skyrim a lot.
