Bad palyers

So, I was on a game as an adc Graves, and I had a support Blitzcrank. After multiple requests to try and grab the adc, not the support, I gave up, and obviously raged. His inability to change lost me tons of cs, kills and the lane eventually. He was with his friends on the game. A top lane Garen and a jungle Vi, they refused to accept the fact that this blitz wasnt even trying. They got along with the opposition and got me banned for 14 days.

If you simply remove the cause of toxicity and rage, isnt that making a better community, than simply punishing the rager or the toxic player? Just because he had his friends, I got more reports against me. What happened to teamwork and all that you talk of? I may not have raged at all if he was trying and not able to grab. But he wasnt even trying. I also agree he maybe having a bad day, but that dosnt mean i can keep my cool all day. After asking 3-4 times to not grab the support, I lost it! And anyone would. So Im not able to play for 14 days, while a bad support and his friends are on the game right now, spoiling someone elses game, and probablly getting him banned aswell! Excellent system!
