How to nerf high tier Riven play

Okay. It is quite simple in my eyes, as Riven has a negative win rate until Diamond, it is obvious that she is only good in the hands of good players. Her win rate in bronze is 45%, but in Challenger is 56%. How do we effectively nerf her challenger win rate without affecting Bronze? Simple, Bronze 'noobs' are not proficient at weaving basic attacks and doing fast combos on Riven. As such they often waste or simply do not make as much use of her passive as high tier players.

So I think any nerfs to Riven should go onto her passive. I would...

Nerf Passive Ratio: 25 - 50% to 20 - 40%

Should the nerf prove too hard on her laning for low tiers/top tier play. I would suggest a minor increase to her base HP regen

Buffing: 5.34 - 13.8 to 6.5 - 16.0

ONLY of course if she drops too far from the above nerf. As Riven has among the lower health regens in League and thus why she spams so many pots in laning and MUST bully, if she doesn't win every trade drastically her lack of innate sustain means it is lost after a few moments. Buffing HP regen will also prevent the 2 jungle Riven players from being hurt too much by the nerf.

I know this isn't the "GUT EVERYTHING WITH A DASH!" solution the boards tends to enjoy. Which is why Riot ignores any conversations on the topic. But I feel it is a solid and reasonable plan. Since Riven is NOT unbalanced in plat or below. And only becomes too good in Diamond-Challenger. Regardless of the raging of Bronze players, numbers don't lie. The nerf would hit all tiers, but it would hit top tier the hardest, since 'exploiting' canceling and combos is a huge portion of Riven at that level, and the passive is a massive part of the scaling for her fast combos.
