Option to disable /all chat.
Let's face it; aside from Call of Duty, this game has the worst player base among all multiplayer games. Perhaps in part due to the fact we can type while walking, or can stand still without fear of dying. (vs. CoD, where you can be a jerk over the microphone, with no need to stop your action).
Sure, we can mute players.
Why not just add a function to disable /all and/or team chat entirely, every game? There are pings to say anything strategic, and anyone who needs more communication than that is using a voice program.
