Increase ban capacity?

The champion pool is increasing, and we currently have 126 champions to choose from, and another one in the works (or at least i suspect so with the whole "they are coming" thing) and we can only ban three of those 126 (not, of course, counting the enemy team) as the champion pool increases banning becomes less and less effective, and the thing that makes it more effective? Increase how many people you can ban! That's it! You don't have to make 8 or 7 or whatever other random number your mind can think of I guess... Just increase it by one or two, that's all we need. A couple extra bans.
