It would be nice to have an option to have the voice from other players to be positional, ie. have the sound come from their headset position (or at least direction) rather than the nonpositional "god voice" there is now. I believe it would help in knowing which player is speaking, would make it easier to listen to specific player and would make the breathing and other unwanted noise coming from other players less annoying.

Voice from 2D players could maybe eminate from their player spot?

bonus feature: it would be funny to have another option to pitch shift the voice of the players depending on their size, so a player scaled much smaller than you would have a higher pitch voice and vice versa
