Champion Select additional feature
I love the new champion select a lot since it came out this season. There is something I'd like to change though which is the ban phase. It would be nice if your team could NOT ban a champion that's being hovered by a teammate. I've had a game with a pre-made group had the choice of all three bans and they used it on every champion I hovered. They'd even say sorry sarcastically even though the champions aren't ban worthy.
Short: Unable to ban champions hovered on your team during the ban phase.
And I know some people just don't want to play with yasuo or riven on their team, but it's an idea.
