My opinion
This is a suggestion I have for a feature to add to league of legends. As we know ranked players are only able to play champions that they own, but in some cases a lot of players have most, if not all, of the champions. So when it comes time to pick, I usually end up picking a champion I don't know how to play, or have played in small amounts and do alright with them. My suggestion would be to create some sort of a system where an individual player can pick and choose what champions would appear in their pool for ranked matches, that way idiots like me will only have champions that we feel comfortable playing with. That's just my idea anyway, thoughts?
