6 bans is more like an inconvenient phase of the rank process because of how many champions there are. Why not do away with bans all together? Increasing the amount of bans is preferable, but let's face it, probably not going to happen.
Eotw2 votesThere are times when a couple champions are genuinely overpowered or broken, typically due to bugs.
For everything else, there's counterplay.
kcStranger1 votesThis. To be honest, bans can be random enough in solo queue due to the lack of coordination among team members that I had the same thought about getting rid of bans. I really could care less if people get wrecked because they don't know how to play against Fizz. They should learn to play against him. But every once in a while Riot breaks something (e.g., Warwick with the original Skirmisher's Sabre), and there needs to be a tool to prevent that from breaking the game.

Especially at lower elos, a lot of people don't know how to deal with certain champs (kat) and end up losing the game from champ select.
