Because having to listen to screaming squeakers when you’re just trying to play a game is a pain in the ass. 
Edit: Forget what I said, apparently you can mute. It just wasn’t working. So how do I delete this post? ;w;
Are you not able to right now? Just click on their name in the player list, and there’s an option to mute. I’ve never used it, so I guess it’s possible it’s not implemented yet…
Yeah, it just started working, how odd. Previously when I would press tab it would just bring up the player list, no matter what I did it wouldn’t allow me to select anything. But it appears to be working fine now, and I’ll be removing this post. Thanks though!
