Ranked Games KDA Suggestion
Imagine there was a sort of system for people that are doing poorly with a champion in a ranked game. I believe there should be some KDA limit in order to be able to play a champion in a ranked game. Maybe around 1.5 would be ideal. It's not very easy to achieve that KDA in my opinion ,so it is fair. Hence, once you have a KDA lower than 1.5, this specific champion is locked for you and you have to do a certain amount of normal games in order to improve and not just spam champions you have never played before, in ranked games.
