Now that there are so many champs, we should ban 30 during draft.

It's only fair that before a game each player gets to ban 2 champs. There are just too many champs and banning six isn't enough to make a difference in a single game, the likelihood that the opponents were going to pick one of the three that your team bans is just too low. If you ban 30 champs, then you'll most likely hit at least one that the other team was going to use. Otherwise, I think we should just get rid of banning altogether, but 6 just doesn't make a difference.
