More Champ Bans in Draft

There are about 140 champions in the game, and each new one has new forms of cc and tons of escape. While there's the argument that every champion can be outplayed, counter picked, and counter built, you can also argue that by that logic, Riot never should have implemented banning in the first place. My argument is simply that an increase should be made to how many bans there are in draft pick. Increasing it in even increments, choosing a player at random on each team to ban one extra champion for twelve, or every other player for 18, etc. It would allow an ease into having more control over games while still allowing enough champions in the pool to cover all roles and playstyles.
