Mute Functionality - Pings
I rarely actually mute anyone in game, even when they are fairly annoying. When I DO mute someone, they are not only flaming or trolling, they tend to be spamming, and everyone knows if you're muted they still have to see, and listen to, your pings... so most of the time they spend the rest of the game spamming pings.
If you have decided you want to cancel communication from a player all together, why would the system now let them continue to ping you with SFX, Graphics, and more chat spam?
