Too Many Children Playing Ranked

I'm not sure if this post is allowed or not but I wanted to vent a little about how FILLED ranked is with little children. I just want to say that I understand it's a free superhero game, obviously kids will play it and enjoy it. The problem is ranked is swamped with really young kids that are extremely toxic, play as Spiderman, pull a 5:11 ratio, 1v5 then die then blame the team or healers. And this isn't like 1 or 2 games, no it's like every 3 games at least. It's a very frustrating experience, so, any parents here, please watch your kids or have them stick to casual I beg of you.
