Is nothing going to be done about the Top 5 current bans?

So the top 5 most banned out champions as of late are ( na.op.gg source)

1. Shyvana 69.83%

2. Elise 59.08%

3. Master Yi 34.80%

4. Fizz 32.22%

5. Kayle 29.55%

Now I know there will always be top 5 current bans but the reasoning for these bans and % ban rates are currently insane. (with not enough bans to ban out other junglers, juggernauts, assassins, etc.)

Kayle, Shyvana and Yi are all riding the Sated Devourer boat which is clearly a broken item that needs to be nerfed or removed. There is still NOTHING on the PBE nerfing or changing this enchantment which is sad because not a single other enchantment has lasted this long untouched in such a broken state. So something has to happen with Sated devourer because its flat out broken and not fun to play with or against. The damage output on these champions are insane. Better nerf 5 AD.

Now as Fizz he has probably almost always been a problematic champion. Not only can you build what ever you want on Fizz the clear problem is his E. The cooldown needs to be higher because it is too good of an ability to be on a 4.5 second cooldown with 40% cdr. I like the changes on the PBE but honestly if his E is left untouched Tank Fizz will still probably be viable and AP Fizz could go back to season 4 insanity.

And lastly Elise is still a little over-tuned. The last nerf was probably a little too minor of a nerf needed to keep down her dominance and I am sure Riot still probably has their eyes on her.

TL;DR

Riot has a lot of balancing on their hands right now. There are just too many things to ban and the current ban rates show it. Sated Devourer needs clear nerfs, a rework or removal. Fizz is going to need some massive changes to even be considered healthy, and Elise is still a little too strong right now. This patch is just too much to handle with all these nerfs and buffs, Riot is probably scrambling to deal with Skarner at this point.
