League of Legends is famous for its flamers. What about a experiment where the chat is disabled for a couple of days? Or a week? Im wondering how it would be because if we chat, we flame, if we flame we loose... :,c (usually) Thanks for reading :)
I'm afraid that the toxic people would resort to afk'ing or ruining your match through gameplay without a chat to vent in. It's more difficult to catch and punish a troll through his gameplay too, and you can't press a button to stop it.
That, and most people are positive or neutral in chat. Removing it is punishing everyone for the actions of a few. You have good intentions, but I don't think it's a good idea.
