Suggestion For Champ Select

The one thing I hate the most when new champs or skins (like Dawnbringer/Nightbringer) is when you get your role and pick your champ, there is always that one asshole that decides to ban your champ you selected on your team just because they wanted that role and champ. I have queued up for PBE Draft several times to try the new Yasuo skin and still keeps on getting banned by one of my team members. I think there needs to be a feature that makes it when you pick your champ, your teammates can't ban him. I am so tired of trolls and want to be able to play my champions. I love playing league, but when you get that troll that decides to queue into your game and ruins everything, makes you tilt, makes you rage, and you get no fun out of a game meant for players to have fun. I think this feature would be perfect so trolls cant ban what you want to play. Please make this happen.
