Idea to bring a little flavor to champion pools in competitive play

Hello summoners! This is just a thought i had rolling around in my noggin'. After watching countless LCS matches and even professional non-LCS play, i feel like the champion select has become pretty stale. Every game you can expect the same champions (gragas/rek'sai/etc come to mind at this current season). Now, I understand that the current "meta" favors certain champs heavily, but it gets kind of boring watching the same champ selects game after game. So, what i'm proposing is a change to how champ select works for these professional games. Lets say you draft a certain team for game one (keep in mind best of 5's will probably work for this better than b03's ). Once you have chosen that team set up, you should be locked out of it for at least Game 2. Lets say these champs need a "cool down" to breathe, get some water, heal their wounds, cause after all they are human (mostly ) this would force teams to play not just Vladimir or Gragas every damn game would change picks/bans dramatically , and sort of give new life to the pro scene, while making it more fun as a viewer to watch their favorite champ be played ( ) Just a thought, though i doubt this would ever happen.
