But let me ask you this question, why should we have to get stuck with a group of top heavy champions? Trust me, this would be a lot simpler if there were only 6 champions in question that are dominating ranked play right now, you'd just ban them all and the game would be balanced-ish. When gut a single role pre-game, you are fostering a bad habit of extreme inbalance. The main reason why we are at this point of asking for more bans is because the ratio of God Tier champions to everyone else is just high enough to not be balanced through banning, but not populous enough to foster diversity. And since Riot has proven that they aren't getting this crap under control anytime soon, there's only one solution, and that's dropping the banhammer more times. Before Kassadin was reworked, he was almost permabanned in games. Jax was getting pretty damn close to that, and is still hovering around a 80% ban rate, despite what in my opinion is some pretty heavy base stat nerfs.
So here's the question. Why should we have to worry about so many champions who's so overpowered or unbalanced or toxic so much so that we have to ration out bans for specific champions? I often wait to ban the problem champions last to force the other team captain's hand to waste a ban on them, or feel the wrath of Jax or Kassadin. It shouldn't have to come to that point is what I'm saying. Bans are being used as a gotcha game to see who slips up and doesn't ban one of the OP champions atm, and that's not what League is about. The game shouldn't be decided at the champion select screen. So until the balance team gets its crap together (which at this rate is sometime Season 6) we have to resort to drastic measures such as more bans. I'm not saying it's perfect or even a good idea, but it's a necessary evil. It's a choice between the possibility of screwing a lane over, or the guaranteed static champion pool until Riot abandons League. I'm not comfortable with the latter since the main selling point to MOBAs is the ever changing strategies.
With patch 4.10, we're already seeing some new options come in. Marksmen might be coming top lane with the newfound knowledge of the power of Quinn top. Jayce might return top as a result of this as well. But if we don't allow these stubborn and unhealthy champions to warm the bench every once in a while, it will be Renekton top, Lee Sin jungle, Kassadin mid, Caitlyn ADC, and Thresh bot until League dies.
