/Ignore All to make yourself a better player?
Do you think that muting all players makes you a better player? More often than not, teammate's chat messages are posing to be distractions rather than help.
What about muting your teammate's pings? Useless pings are a problem among many games too. Teammate died? Ping. Just did something weird? Ping. Just pushed in your laner's wave like a good jungler? PING PING PING PING. You can just watch the lanes to look for MIAs yourself instead of relying on your teammates to call the MIA for you, who are inconsistent themselves.
