Well with a game as fast pace as this, it would be nifty to use voice chat to type while using my hands to do combat related things. But then... there already are voice chat programs that we can and do use to accomplish the same thing essentially, but with smaller groups of people.

The good thing about something like that would be that it would work for anyone in the game. I would probably use it once I got used to it, but then why not just incorporate local or private voice chat directly into the game integration at that point. One has to wonder.
