* The "Champion Mastery" system should be used to prevent players to pick a never played champion in Ranked
* Summoners have to train 10 champions in ** Normal Mode** to unlock ranked games. (Not just possess)
* At least **one victory** should be necessary to level up to the first tier with a champion (allowing to use this champion in ranked) - *Players motivated by a goal, play better. And so the games are going better*
* The system could be retroactive, avoiding to experienced players to trains all the champions they already know.
* The "Champion Mastery" system start at **lvl1** and not** lvl30**.
