10 Bans for Ranked

Season 1 had something like 65 Champions and their were 6 bans in a match. That leaves a pool of approx 90% of the champions playable. In preseason 7 their are now 123 and with Camile that puts it to 124. With 6 bans that leaves approx 95% of the champions playable, and with 10 bans it puts it to about 92% of the champions playable, which is about the same as season 1. Personally 6 bans a team would be nice putting in at around 90%, but i feel as if 12 bans is a little much. and with more bans riot would not have to try as hard with buffs and nerfs because of the visibility on those champions that are banned. with 6 bans you can only get rid of so many of the strongest champions and there are far more than 6 at this moment. I'm just wondering everyone's thoughts on this. Am i wrong in thinking we need more bans in ranked games?
