Are too many 'OP's' a good thing?

Disclaimer: This is my opinion, I tried to desalinate this post as much as possible.

I think that the more champs you have to ban means a game isn't balanced. If a game had too many things to ban, you just take what is left over, and that is bland. That would cause people to play and see only a very small amount of champions just because people consider them to be 'OP'. If you have a small pool of champions that are so much better than the rest, why play who you like to play, play what's OP.

These are all the champs that I consider to be good bans because they are so strong right now:

All of these make a complete team comp. Say your team gets , , and , but the enemy gets only , it doesn't seem to matter about player skill. It only seems to matter about who has what. The ELO I play in is around a gold elo and this seems to be the case. What do you guys think about having too many champions that dominate everything?
