The thing Is, they aren't. The reason for that misconception is K0nfig, he is not toxic or cocky, he is confident, he has never stated he is the best (correct me if I am wrong). He tweets about being able to beat everybody, that is confidence, not cockiness. If he starts doubting himself his performance will get weaker, but as you clearly saw from that second map today, he was confident, and it paid off.
And people who say MSL is a bad IGL should get their head out of their ass.
