A feature to help improve player behavior.
We have all been in situations where the game becomes frustrating. Some of us have poor means of handling this frustration and lash out at teammates. I propose a new feature which could help players release that frustration without directly effecting team atmosphere.
"/Mute @self" - This feature will let the player type in the chat, and it displays their messages in the chat, but only to them. The messages do not show to other players. This way a player can rage, yell, and type, but without the expense of teammates being belittled. It is also an active choice for players to make, and honestly its better alternative to bottling up that frustration.
