BAN MORE CHAMPS IN RANKED?

Hello I am Pink Tyrant, i message you today because I am exhausted of the the abuse of champs such as Syndra, Lee Sin, Darius, Riven, Yasuo, etc. The point i am trying to present is the fact that there are too much over powered champs in league of legends. When it comes to ranked games I am usually distraught because only six champions can be banned yet there is a much greater champion pool of over powered champions. Lately I have noticed that i do not lose a certain amount due to the way me or my teams, but solely on the champion selection. I understand that it takes time to fix these champions and reducing their abilities by a great amount me remove them from the meta. I do have a suggestion for this. You may create more items to strengthen counter play, increase bounty on fed champions according to the amount of time they stay alive and the amount of kills they have, or increase the amount of champs that can be banned per ranked/draft games. In my opinion the last option would be the best case scenario because it would be the most efficient way to reduce the amount of overpowered champs participating in ranked games. The reason i say this is because it takes little calculation, very little costs to put this in a patch and this would make sense as there are now 134 champions in league of legends. with 134 champions it is very difficult to reduce the amount of overpowered champs in one game due to the fact that we can only ban about 4,5% of total champs. As a player who has been playing the game since season 3 and still wishes to play the game i strongly urge you (riot) to move towards this method. Thank you.
