Only MASTERED champs eligible for ranked play

Your thoughts on having only MASTERED champs eligible for a player to use in RANKED? - Only MASTERY 5 or higher can be played in RANKED, maybe? - eliminate the "first time playing..." - more assurance of the player knowing their champ better - encourage player to practise more champs to cover more lanes - etc Keen to read your thoughts, the climb is frustrating enough as it is without having team mates who have NO IDEA how to; use, build or play, their champ adequately. I'm writing as a bronze/silver level player.
