I haven't ever wanted to use any of the voice chat apps, because I don't want to hear the voices of the Players in my ears, I want to hear the voices of their Characters in my head.

If I ever did decide I needed it (I don't do the Savage tier raids) I know I'd first learn how to use a voice-altering bit of software and ensure I ran the voice-altering software before launching voice chat.

So me. Never raided Savage. Outside of Savage, never needed any vocal direction, just "Know your Job, Know the Fight". It's easy to play with JEDF selected, knowing only E, then...
