Finally i think no one is really talking about VOIP. Probably the most people are happy with it.
First of all I like the VOIP feature and its “3D” – approach. (as a first iteration)
What I would like to see (maybe it is already planned or inside the game):
1. Volume control keep it simple but whispering (2-3m), speaking(5-10m) and yelling should be an option. What I noticed so far that the distance where people each other is pretty large (What I would consider as yelling).
2. Mute individual players. Everyone who has ever played a game with ingame VOIP knows this problem Some funny guy plays the actual Katy Perry Soundtrack at full volume.
3. Communication channels
a. 1. Channel Speaking to everyone nearby (in the same vehicle)
b. 2. Channel Speaking to everyone nearby and on a com channel (Squad-Radio)
c. 3. Channel Speaking to everyone nearby and on a second com channel (Command-Radio)
d. (More channels would be great)
4. Make Comchannels assignable to one ear (left or right)
You might have noticed I am a tactical Arma player. And that’s something which has been realized in some mods AND it is a very useful system.
Regarding point 4. For a Squad Leader or his designated radioman who is talking to his squad and his command makes it a lot easier to separate who is talking to him when one channel is solely on one ear.
