It takes 15-20 in game seconds to mute everyone/everything in game.

So some guy suddenly spammed pings almost bleeding my ears at 30 minutes into the game, so I stayed back and started muting people that were following up on the spam, our inhibitor gets destroyed... CAN WE HAVE A MUTE ALL BUTTON, I DON'T TRUST PEOPLE IN NOT SPAMMING PINGS SUDDENLY, I SUGGESTED THE PING VOLUME LONG AGO BUT THAT DOESN'T STOP THE CHAT FROM BEING FLOODED WITH RANDOM ALERTS AND MAP BEING HIDDEN WITH THE HUGE BLUE DOTS. (seriously the map is too small, before it was too big post fix....) I always seem to get people where they think that spamming smart pings makes them smarter.
