The inability to say anything is appalling
Since the new system has been established and big brother Riot is overseeing everything you can't say anything, anything at all about the state of the game.
"Stop fucking feeding, you need to play safe" reported "You need to buy a ward so you stop dying to the obvious gank I keep pinging out for you" reported "I can't fucking believe you died to that again, you had 10 seconds of pings to run the fuck away" reported
Notice there's some naughty language (oh no) but that's how things work sometimes, especially in a competitive game where the point of ranked is to climb. It's insulting to everyone trying to win to call someone out on going 0/4 in lane and have the response be, "I don't care, I'm high and just playing for fun"
There are game modes for playing just for fun, even when high. They are not the ranked ladder system. And don't you dare call that cocksucker out for being a douche and wasting your time because you'll wind up reported.
If this is how the game is being handled I don't even want a chat option because there's no point in having one. If you aren't allowed to say ANYTHING negative at all then why have a chat? Guess what the world is negative and you're going to experience negative shit in it, grow a pair and back the fuck up when your teammates tell you to, you'll be better for it.
Now downvote me since I know all you children can't exist without uncle Riot coddling you and keeping you safe from the meanies of the world.
