i have tested the game this week end, and i think that you should add a 2nd voice channel.
The first for the team, and the second for the players nearby.
Why it's important : because in a fight, we give informations for guyz around, but not for others players of the team.
A brief information given to fighters around us can be good and useful, but can confuse another teammates who are at another place of the front.
Please add this channel because teamplay is a key for the great life of this promising game !
