Why there's no nerfing plan for Jax the highest ban rate?

To quote many a Rioter,

Pick and Ban rates are good indications of trends in the current state of the game, but are not the sole factor in considering champion balance.

I'm paraphrasing but meh.

Jax is particularly annoying for me and has been for awhile, he's string, but I still don't think he's overpowered. A good Jax can wreck a lane and a team sure, but I imagine it's more just the flavor of the month kind of thing.

Also keep in mind pick/ban rates are different throughout skill levels, which can also affect the consideration.

Jax hasn't been buffed or nerfed in ages. People are just complaining about him because he is "FotM". Also, if your only argument is that his is the highest ban rate, think about this: there will always be a champion with #1 ban rate, and #1 win rate. Does that mean we will always be nerfing champs?

Jax, Teemo, Wukong cooldown decoy thing, Vi.

Yasuo - Their in 8/10 of my games their is a Yasuo that is un solo-able by mid game. That needs to be changed.

AHRI - survivability is insane.

MASTER YI MASTER YI MASTER YI MASTER YI

I have had enough with dealing with these champions , they are ridiculously overpowered, whther it is there kits (Master Yi, Wukong eg) or pure damage mixed with insane survivability or escapes.

why should I not be allowed to play my favourite champion , because come mid- late game if I or the rest of the team hasnt performed I become a liability

where as a teemo or a jax could die 10 times yet still come out on top.

It must be that Riot loves using these champions themselves so the avoid discussing these Ridiculous anti-fun champions; I dont see the discussion so that is the only answer for me.
