SirhcEz should be the model of good League behavior
Look at this guy. He gets flamed, and just ignores it. He's very much aware that people are talking shit, but he handles it in healthier ways than flaming back, such as by turning the flames he receives into clickbait titles/thumbnails for his youtube channel. I have never once seen him actually lose his cool in game, and I think his rank and success are a testament to that.
To those of you who have been restricted or banned for retaliating against other flamers, please check this guy out and consider copying his behavior. It's simply not worth it to get angry because some guy on the other side of your computer screen is needling you.
