I just want to comment on Rek'sai : the rework no one asked for. Why, instead of bashing your own idea of a champ into our heads, don't you just accept that Rek'sai is a good tank? You made a good tank. No one that plays her think she needs a rework, they enjoy her kit and have adapted to the nerfs over her lifetime. Speaking of nerfs, you nerfed her because she was a super powerful AD diver, and now you're talking about reworking her to be a super powerful AD diver. Do you really, honestly, not see the problem there?
You already tried to have her be an AD diver, it didn't work, now she's a great tank, contested pick but not OP, and you're going to go back to the drawing board to try that failed idea again?
Leave her as is, and take all your cool ideas for a super powerful AD diver and apply them to a new champion (cough, Camile, cough)....wait, DON'T do that, and instead try making a balanced champion next.
The point of this is that years ago you accepted what your community did with your champions. Things like Annie support, AP Ezreal mid, or other "off meta" or "off role" picks are great, you don't need to sit there and go "BUT WE WANTED ANNIE TO BE MID!" or "BUT WE WANTED REK'SAI TO BE AN AD DIVER!".
Instead, embrace how your community was able to adapt to your constant nerfs and meta balancing/updating and created a happy role for their favorite champion.
