When is ping-muting gonna be added?

I'm only assuming it's going to be added soon because it's been a very needed thing for so long.

When you mute someone for toxicity/harassing you/or you just plain don't feel like listening to them, they're obviously pissed at you as well. So are they just gonna let you have a happy game? No! They're gonna try to make you miserable by giving you that constant annoying noise a ping makes.

Just give us the option already. I don't know why it hasn't been added yet.
