One year ago RIOT released a dev blog about the criteria they use to buff/nerf champions. Here is for easier access.
My main focus is the d2-challenger tier, where a champion should be nerfed if they have more than 50% ban rate for 2 patches in a row, which did and it still does apply to lulu to this patch since patch 11.10 (11.11 depending on the site you use).
For u. gg :11.10, 11.11, 11.12, 11.13, 11.14
For lolalytics: 11.10, 11.11, 11.12, 11.13, 11.14
Does riot simply not follow this anymore? Or is this an oversight?
EDIT: Riot confirmed this is not the case and their internal data don't show 50% + ban rate!
I'll let the post up for discussion and information.
