Why is chat a thing?

I dont see the point of Chat exsisting! Only thing that happens in chat is flame these days! You can communicate EVERYTHING With pings! So please riot give us a option to remove chat if we dont see it, /mute all is for me,but that player will still spend time typing rather than playing. Every game people flame its not even funny anymore,i say "hi" and people spam report x for the next 20mins,games are so bad i question why i even play League anymore!
