"Plz report X for Y" and the Summoner's Code
I think the Summoner's code is the best thing to happen to any gaming community. A clearly defined system of behavior that reflects the eccentricities of the game involved, with a clear punishment system to support it is just what these communities need to limit the toxicity that seems inherent to many gaming communities. Revisions like adding Pick>Call have reinforced these ideas, and have reduced the amount of rage I've seen a great deal.
That being said, there is one common sense addition that I view as necessary. Asking for a team-member to be reported in all chat is never helpful, and often causes the person to get even more toxic. I understand that it is frustrating to play with a toxic player, but can it wait until the end of the game? Besides, I have never reported someone based upon an All chat comment other than "AFK" or "Intentional Feeding," as it becomes a game of he said, she said.
Please Riot, Add a line to the summoner's code disallowing or even just discouraging allchat report requests, with the caveat that players can ask for an allchat report in the postgame screen.
