There's a mute button for a reason; if you're a sensitive person, use it.
I've recently starting playing LoL again and it seems like the amount of cringeworthy hypersensitive people has gone up significantly since I quit. I've been reported my past 3 games for simply calling shots and instructing my team on which objectives to push when they are all over the map. I don't personally attack anyone for their play-style or mistakes, because it usually doesn't help.
I've also noticed people will report others for trash talking, when that's a part of any sport. Even for saying shit like "Haha easy game" afterwards.
Seriously, are we all in middle school again? Are you people that sensitive that you can't handle banter? Were you raised by a single mother or something?
It's pretty annoying and really takes the fun out of the game when you can't even use the chatbox without getting reported. So, like I said in the title, if you are that sensitive to where you can't handle interacting with other human beings, use the mute button.
