Please understand the real balancing issue with Riven.

Riven has been going strong for quite some time now with a high pick, ban, and win rate. It's clear she needs to be observed and adjusted accordingly, but we have to identify the real problem.

I believe it's the fact that she has such a massive safety net on top of her absurdly strong early game dueling power. She's a fighter/assassin that can kill tanks, fighters, and assassins alike. There is no other assassin in the game that can 100-0 someone and also have no trouble with fighters and tanks (who naturally counter assassins). Riven is the only one capable of doing so.

On top of this she has a resourceless, low cooldown safety net of dashes and an AD scaling shield. This makes ganking her very difficult, impossible if she wards. By the time her 4 dashes are on cooldown, she's standing under her turret. This is an obvious problem when it's so difficult to 1v1 her in lane. Even worse, she has 1.5 seconds of hard CC mixed into her kit for some reason.

So how does this come together? Her trading power is unlimited. She has no mana issues to hold her back from jumping in, bursting you for 60% of your hp while you're stunned or knocked up, then dashing away and shielding any damage she might take from you. It's the fact that she can burst like assassin but has hard CC to remove any counterplay.

Now let's look at her counters.

Honestly I don't know if he's going to be a decent counter to her anymore, especially with his silence nerf. We will have to see where his rework takes us before casting judgement. My personal favorite counter to Riven, but he has 1 glaring fault. His sustain pushes the wave. This means that the best way to counter Riven 1v1 sets you up for a 1v2. This is a very dangerous and unreliable counter, and I don't think it's adequate. Also being reworked and is notoriously easy to gank at any point in the game. Probably the best counter to Riven although his axe can push the wave and she can beat him pre-6, which is her most oppressive time in the game. This basically leaves Shyvana as the remaining half decent counter against Riven, and unlike other matchups such as Ahri being completely rendered useless by Yasuo, this is only a minniscule advantage. Riven's spontaneous ability usage will allow her to outplay a good amount of Shyvanas.

Just because she has 1 or 2 half decent counters doesn't mean it's okay for her to stomp 95% of the other champions in the game. You can't even stagnate the lane into a farmfest or anything because of her 4 gap closers. You either lose CS or you die.

So here are the best options to give her more counterplay, or tbh simply get rid of her lack of counterplay:

1. Give her resources whether energy or HP or mana.

2. Adjust her cooldowns. Her entire kit is spammable, which is made into an enormous issue when she doesn't use resources and her full kit spam is uncounterable. Adjust her shield CD to allow her to be poked down, or give her 3 dash Q a more reasonable timer so that she's actually catchable. Her best counterplay is hard CC (which is true for nearly every champion) but the only CC that can stop her almost always has a higher cooldown than her kit and high mana costs, limiting it's use. Riven can jump back in a few seconds later while any CC is on cooldown and blast your ass to bits.

tl;dr People don't take into account the fact that her 1v1 potential is nearly unrivaled, she is extremely hard to punish with a gank, her low cooldowns and resourcelessness allows her to pick and choose her battles, and she can simply avoid her counters altogether or punish them for pushing the lane. Rebalance her power, her CC, or her spammability.
