So if the player is being toxic because they are stuck on a losing streak, making them end up in their worst role every game so they have the least possible chance to win... is supposed to somehow prevent further toxicity?
I get frustrated when I'm on a losing streak and then don't even get to play the roles I'm best at. I think this is a terrible idea.
Really hard for me to NOT be toxic when I call a lane pref, then first pick takes it... I call another lane pref, and second or third pick takes it... at that point it starts getting hard to not just troll. Especially on a losing streak already. Then you just KNOW if you do badly on your worst pick, the team will blame you for it and that will just set you into a toxic frenzy.
