Chat is also there for that, for players to ask for help when they need it.
You're free to help or not, no one's forcing you.
And there's a universal rule: you will be treated the way you treated people, one day you're gonna be the one in need of help, and i don't think you'd appreciate it if anyone tried to make it hard for you to get that help.
And as Sahphyr mentioned, our chat presents real serious issues like regular trolling from some of us, and also racism, bigotry, misogyny, and insults of all kinds, and at times people talking about their botting / cheating activities or holding any kind of private conversation in public: those are the things we should question, if we care about being a part of a healthier community.
