Just fast chat, nothing else, it is a way of communication that can rlly help some times, the difference bettween this and the normal chat or voice chat is that it is not free coms
Example of it:
Player1945 ( Hawk ) > Need Healing [ 240k Hp missing)
Player1945 ( Hawk ) > Focus on "Player 3212 ( Kid )"....(Not telling the bot, only if it is a Titan)
Player1325 ( Hawk ) > Get C beacon
Player1325 ( Hawk) > Need help!!
Also when U say something like the "Need help!!" ur username in match probably could Blink for a while.
Can also add a mute setting and a limit of 5s between every message. And also be able to edit it, for example deleting the nametag of the player in the chat or the robot.
I think that it is a good way to add a better team communication.
