Please stop asking...
I get why a lot of people want more bans per game, but queues take long enough to get through already. You shouldn't think of bans as way to remove 'OP' champions from the game, you should use them to block champions that counter your team comp. For instance, ban Vayne if you have a tank comp.
If someone is strong in the current meta, then let your team play it instead of asking for 10 chances to ban it from the game.
