Interesting facts:

• Darius, Fiora and Tahm Kench remain the top 3 bans.
• Graves, Yasuo and Caitlyn are the top 3 picks. 4-6 are Lee Sin, Thresh and Riven.
• Graves and Yasuo, although not in the top 20, sit at 53% winrate and 35-40% pickrate. They're also 5th and 7th top ban respectively.
• Riven has dropped to 44% winrate (mostly due to item and mastery changes).
• Soraka is stronger than ever, with 15% pickrate and 53% winrate.
• Kayle's winrate in higher elo climbs even higher.
• Kog'Maw is siting at 41% winrate

Keep in mind that champions with high skillcap or niche playerbase are expected to have higher winrates, while popular but difficult champions are supposed to have lower, even sub-50 winrates (with mains having individual winrate above 50%).

What I'd expect, looking at that data:

• Trynd and Yasuo will be covered with the upcoming hotfix to Warlord's Bloodlust
• If that isn't enough there might be nerfs to them/their crit passives in particular
• Tanks did not really change their winrate that much, and are mostly benefitting from people mindlessly picking full AD comps
• Buffs to Sion and Sejuani will come faster: in patch 6.14 instead of 6.22 :P
• Malzahar, Vel'Koz and Brand are supposed to perform that well since it's mostly their dedicated playerbase who picks them
• I would expect nerfs to Brand in the support role, unless they want to shift him there
• Kayle with the new Guinsoo's Rageblade is insane, nerfs wouldn't surprise me
• MF nerfs, Kog'Maw buffs
• Riven buffs?
