PSA: 10 bans cannot ban out any roles
http://champion.gg/statistics/
Before you go whining about the possibility that all ADCs get banned out. No, they don't. The only way someone could not potentially play an adc is if every ban and pick is an adc. Then two people can't play ADC. Can't stand the thought of having your meta banned? Most of those champs are below 50% winrate. Pick what works for you, and you won't have to worry about bans in soloQ
EDIT: It seems this thread has picked up a bit. Here's a few responses/explanations/solutions:
Both team captains are somehow on the same page about bans. They will rarely be. Assuming captain A has a vendetta against adcs, and captain B sees a jinx or sivir ban as worth while, you'd get like 7 tops, assuming captain A doesn't ban those first. This is why I save what I believe are the enemy's likely highest priority for last. If they ban something I would have banned anyway, I get a free ban, essentially.
We have other options for pick and ban. Instead of giving the team captain 5 bans, we could give everyone a single ban. I believe this will skew the bans toward lane counters, which will make banning out of a role near impossible, since everyone has to cooperate on both teams to do that. We could also go to the dota p&b style, which allows mid pick phase bans. This allows a significant increase in strategic banning potential, and reduces the blanket effect of those later bans, certain champs can slip through in the first pick, while their synergies are then banned off.
If you play nothing but meta picks and are worried about getting banned out. You already have that problem. Work on some pocket picks. I doubt you leveled to 30 on meta picks, and I don't know about you, but my Karthus is still a fucking beast, even though I rarely play him anymore. Fun fact: if you pick off meta, people tend not to know that matchups. Someone picks jax into singed? That guy is screwed.
10 bans doesn't magically open the possibilities that you get completely banned out. The possibility exists with the current count. Does it increase the risk? Certainly. This is the kind of thing you go into ranked with a backup plan for. You ability to prepare is part of your overall performance, and adapting to the changes is key to reaching or staying at the top. As a jungle main, I'm pretty sure I have authority over damn near anyone on this, since it changes in ways that should by all logic make 10 ban deniers physically sick.
The thing about banning is that if you try to ban one thing, it opens a hole for another. Want to ban flex picks? You can't ban all ADCs. Want to ban meta? You're not hitting your lane counters. There's inherent tradeoffs and risks to what you do and don't ban. END EDIT
