Visual Indicator for Player Communication and Mute Notification
Sound icon when somebody talk.
I would love to see who is calling for ammo or medkit etc. Also some people can be really loud and annoying and I would love to be able to mute them. Right now I have to mute one after another until I find the right one.
I would not mention this if the game wasn't so much fun. This is the only thing that really breaks my experience.
I would also love a notification "you are muted by nickname". That way some squeaky gamers could maybe notice that they are annoying and because of that they are loosing the ability to communicate with others. It would give them a hint that they might wanna improve their behavior
