Respect roll for midlane or eat your -30 mmr!

There was windranger in my last game he directly picked mid lane, then I rolled 90. He refused to roll, then I picked tiny. After I pick tiny, he rolled lower than me and did not leave mid. I played with windranger like a ball during whole game throwing him to enemy (he can not disable help for tiny's toss). Wind died 18 times during the game. We lost! I got overwatch ban. Why is it unfair to beat the sheet out of someone who deos not respect roll for midlane? Why I get overwatch? Also, it was my 2 nd game I played tony airlines on the last 15 games. I still am proud of myself, 0 regrets. Might I be a bit aggressive? Ranked roles match games also takes too long to find as a midlaner. I was so satisfied to see that windranger sad. He might be hitting his pc screen after the game. Well, if you want a lose, I can give a lot of losses as it is not a problem for me to win as a fine midlaner.
