When are we getting more bans?

League has had a max of 6 bans for a very long time, with the much larger champion pool of today, more bans would help with handling the large amount of champions that are simply better than the rest. They are always a specific set of champions that will always be banned. Why not add an extra ban for each team, so people can actually ban champs for other reasons other than banning the same 6 fotm champs for the current patch. (Im looking at you, mundo, soraka and friends).
