Tired of having teammates accidentally ban hovered champions

I see this problem ridiculously often, in champ select it comes to a player's ban turn, and they aren't ready, so they panic ban a champ. Next thing they know a teammate is raging at them for banning the champ they wanted to play. This would be easier to avoid if hovered champs had a different particle around their portrait in the champ select window. It probably wouldn't be that hard to implement either.
