Meanwhile these guys and gals

None of the mentioned champions had an 8% winrate increase while also becoming way more popular in a single day.
The more people play something the lower, or closer to 50%, the winrate should be, just by the law of averages. His winrate AND playrate increased significantly and that's just something that shouldn't happen.
Not to mention that almost all of the mentions got nerfed already.
Hey galio is fine now, and Orianna just needs higher early Mana costs.
Why are you still whining about Fiora after she's been slapped with a triple-threat nerf (once Urgot comes out)?
