Troll Banning Your Team

Have you ever wanted to play something new in the meta, like when Ezreal jungle first started showing up, but one of your teammates banned it out because they didn't want you to play it or they thought you were trolling? This post is basically me arguing against players having the ability to ban champions their team is highlighting/hovering. I know there are some arguments to be made as to why it should be kept, but they aren't good enough, plain and simple, unless one of you know something I don't with this mechanic. Let me break this down.

You're an Ezreal jungle main. One of your teammates hates it when his teammates get the champ because the Ezs they get always suck and can't land anything, so they ban you out. That's not only troll, but unfair. Why should someone else have any control over what I play? Yes, I know people pick troll picks, but making so you ban their troll pick doesn't solve anything! They say they want to Soraka adc? Ban it, and they'll pick Janna adc. It does not matter. What does matter is the situation above, where someone doesn't like people in their elo playing a champ so they ban it regardless.

You can't stop a troll player with a single ban, but they can ruin your time with theirs. It's lame. Make highlighted champs unbannable by your team.
