Make it so people can't ban the champ you have selected

There's many times where people bm players in champ select by banning champs they have selected, and this is clearly the opposite of the actual intention of this feature. It would be best to prevent this outright by making it so if your teammate has a champ chosen, it makes it so fellow teammates cannot ban that champ at all, or make it a reportable offense to bm teammates as well as logging pre-game lobby chats and actions allowing us to report people outside of matches so that you can dodge and still report said players.
