New Champion Select

Why the hell allow me to pick a champion that I would like to play for the game and yet allow my team to ban said champion? This is just another way to allow this toxic community to troll people. And before you ask I picked shyvanna to jungle so it wasnt like I was picking a champ that was suited for the roll I selected. I really dont get why you would even allow MORE TROLLING in this game. There are enough ways to do it....
