New ban system isn't great, but it's not worse than how it is now
Right now, we have 6 bans. In the new system, it is theoretically possible to only ban 5. It's really unlikely that will ever happen, though. Most likely, we'll get about 7~8 bans total, since there are champions with very high ban rates. That's not amazing, but it's still better than what we have today. It also takes shorter time, which is a reason why a lot of people don't like playing draft queue.
Feedback is nice, but don't go crazy on Riot for this. It's still an improvement, although not a perfect one.
