A lot of maps when you first join the server or while you're dead you'll hover near a position of the battlefield where you can listen on to any nearby voice chat. This is frequently near objectives but I've noticed the positions are not consistent throughout the round. Dunker church... Bloody Lane... Pry Ford and more put the defender at risk of
involuntary espionage from invisible floating enemy waiting to spawn.
I'd recommend either putting the locations higher up in the sky (where you can't hear voice chat) or muting the enemy voice chat to dead players after a few seconds until they spawn again (other than spectators hopefully some day in a separate spectator team status). It's not the type of thing people want to worry about when planning. Various times when we overrun a position and enemy dead are strewn about there's the same urgency to not give away our next step to players still conscious for ten seconds or more. I feel like their ability to listen in should not exist like that.
