Riven: A healthy winrate but an unhealthy playstyle - Rework or leave be?
EDIT: I'm seeing a lot of downvotes, while when I posted this originally on the wikia, I mostly got upvotes, so I'm wondering: Why are you downvoting? Can you please post your explanation on why you think this is a bad idea?
When looking from a balance view, Riven is a bit of a conflicting champion currently. On one hand, her win rate is perfectly fine, but on the other hand, many people absolutely hate her.
It's understandable. Riven may feel balanced to the player, may have a normal win rate, but to an opponent, she feels really strong, even if not handled by a really good player. Keeping her in this state may not be unhealthy if you look at statistics, but if you add emotions to the mix, changing her is a far better idea.
However, considering we already established Riven isn't actually overpowered, she shouldn't be nerfed. That would just make her a useless pick and it wouldn't even remove her biggest problem. Which is Wind slash, by the way. Not her shield. Not her triple Q. That's part of her intended playstyle, and surely not more annoying than a Tristana jumping away, a Blitzcrank pulling you in, a LeBlanc bursting you or whatever. Riven's real problem is part of her design philosophy.
That philosophy is one of a fighter game character, as Morello stated in her mechanics preview all the way back when she was released: You combo abilities in the way best in the situation, and when your enemy is low, you end him with an epic finisher.
When designing Riven, however, one thing was forgotten: League of Legends is a team game, where fighter games are not. This meant that if someone else - say, Zyra or Orianna - were to burst the enemy team to low health, then Riven could double tap R to finish them off. In other words, Riven wouldn't need the combo in order to use the finisher effectively.
Now that we know where the problem is, it's time to solve it. However, we have to keep the execute part in mind. It is, after all, a core part of Riven's playstyle. What can we do, to on one hand remove double tapping R for a multikill, but on the other hand keep her execute in there? Reducing the range would be an option, but I don't believe it is possible to reach a good spot in between too much and too little.
No, a far better idea would be to outright remove Wind slash and replace it with something else, namely a next-ability-buff, a bit like Karma and Heimerdinger have, though not the same because they don't have the aforementioned combo philosophy. The idea is this:
Whenever Riven fights a champion and/or uses abilities and enhanced autoattacks, she builds up a resource she will be given - Ki. This buildup is by far the strongest when she combines the two ways of doing it - putting a full combo down on a jungle mob isn't going to get you enough Ki to actually do something with it. Also, you earn and lose (you lose it when not fighting champions) Ki faster if you have more of it.
Now, when she has built up a certain amount of Ki, she can spend it, using her ultimate key. This buffs up her next Q (one of three only), W or E, and puts the ultimate on a moderate cooldown. However, and this is where it gets unique, Riven can also ult when she does NOT have enough Ki, in which case her ult will look mostly like normally, automatically build up Ki over time (once again not enough to be able to use a buffed ability if you don't use any "normal" abilities in the duration), and she can then ult again if she has enough Ki, buffing up just like before. This will put the ultimate on a long cooldown.
Time to move onto her ability buffs, and the E change that I believe would do well too:
(note that this ability buff is instead of Wind slash, and supposed to be equally powerful but easier to anticipate for the enemy, and therefore healthier)
Q: First or second charge: Gains bonus range and damage and stuns enemies hit. Third charge: Leaps into the air and slams down at target point (moderate range), knocking up enemies hit for a short (but longer than normal) duration and slow them by a large (but not huge) amount for a few seconds afterwards. Once again, keep in mind you can only buff one Q charge, not all three.
W: Deals increased damage (think of 50% more) and stuns slightly longer (1 second). If Riven autoattacks a stunned target, she deals a huge amount of bonus damage. Can only happen once per stun. Bonus damage cannot crit.
E: Normal E: Costs Ki to use when not facing an enemy champion. If you don't have the required Ki, you lose a % of the shield's strength depending on how much Ki you miss. Buffed E: Gains bonus range and shield and shields for longer. Ki costs do not add up.
And her new R:
Now passively gains a smaller amount of AD when not on cooldown, increased when fully ulting (the long cooldown one). When fully ulting, gain bonus range on abilities. Full ult ends when the buffed ability is used, and cannot last more than 15 seconds.

I don't expect you to read it, but in replies I may refer to it. Just so that you know.
