We need more bans
We get 6 bans. Those 6 bans equate to less than 5% of the champion base. And with the steady stream of OP champions running around in any given meta there is no way to ban them all out. So as a means of making bans more impactful we should get 5 bans as a team. That still equates to only 8% of the champion base but at least then we might get to see some champions we don't always see every single game.
