"Braindead champions"
Problem number one: That's worse than making an insult using any term referring to autism.
Number 2: You just don't know how to counter the champion, or know how they work. I mean even
can be crushed with relative ease if you know the way.
Number 3: You're so angry that you have to flame your opponent for doing well? Well I am sorry, but my job as your opponent is to make sure I win and you don't. That goes with any other game or sport.
That said, I think this should qualify as reportable.
