Is there really any point to have Riven's E shield scale 1 to 1 with Bonus AD?

tl;dr of the post for those who dont want to read the entire post: E shield is a bit powerful, so lower the ratio on E instead of weakening the base.

Why Ask This? Valor possesses a short cooldown (3.6, but shield persists for 1.5, making it have a CD window of 2.1) with 40% CDR, which is not hard to get considering she always goes Sorcery to get the free 10% at level 9. If she gets enough AD she barely takes damage with this shield as she heals all of the damage done to her back with her Death's Dance. This is due to the fact she builds a LW item, Leth Item (Ghostblade) and Black Cleaver, meaning she just ignores a good amount of armor to give her a lot of healing from her damage. Also Death's Dance's healing from damage is 33% effective on AOE, which her main damage spells all do. Count the fact Spear might get added to SR in the preseason, and you have the makings of a god in the right hands or maybe anyone at that point. The base shield amount is actually balanced imo, as its not extremely high and its a shield that wont have any heal shield buffing items affecting it because Riven builds none of those items.

This "should" be addressed in the preseason or at some point, because its pretty obnoxious if you smash her and all she has to do is get 40% CDR and 3 AD items and she just kills anyone, including the fed person who smashed her while soaking a lot of damage. Considering she should be mainly balanced around her mains since her playrate outside of her mains is likely as low as old Aatrox, her current winrate strikes me odd when I recall Riven "mains" complaining their champ is too weak and needed buffs not too long ago. Her only "true" counter is CC, which obviously made her weak in the Tank Meta. However, we don't live in such a meta anymore, yet she gained more power despite not being the target of any power changes (Other than a health regen buff and Ult cdr buff). Some of the changes she got in the old system were balanced, where as with the new system, these changes are now (or might be) a little bit over the top. This is not an issue that is limited to just Riven: This affects MOST of the champions that existed in the old system because almost all ratios remained the same, but champ base stats were changed, some items were changed, and keystones are more dynamic than they were in the old system. Later down the road it will be easier to judge what is weak and what isn't with this new system.

Suggestion And Some Math. The shield should honestly have the ratio be lowered from 100% bonus AD to 75% bonus AD or 70% bonus AD. Why do I bring up the ratio and not the base? Because of this: (Used Practice Tool Lv 18 Riven 40% CDR (20 Min in) since the ratio is based on Bonus AD, meaning the base ad she gains doesn't affect her E and other spells, minus the passive which scales with % AD.) Full Build- 3 Items- Everything: Full Build /w Conqueror and R- 667 shield 3 Items /w Conqueror and R- 529 shield Minus R: Full Build /w Conqueror- 572 shield 3 Items /w Conqueror- 457 shield Minus both Conqueror and R: Full Build- 537 shield 3 Items- 422 shield

The Purpose of this Post Why I want to post this is because something like this just flies below the radar when people mainly talk about her being balanced or unbalanced, as her ult , Q, or damage in general are the main points always talked about. Sure, I have Yasuo as my highest mastery champ, but if you look at what I've played the entire year you'd find a lot less Yasuo than you'd expect. To quote Doublelift from his very popular video, The Downsides of a Constantly Evolving Game, "I think there should be more of a focus on buffing what's weak then cutting down what's strong". Why does this point apply to this post? Because everything that was strong against her was cut down via nerfs, while she got "buffs" from said changes. Also in the buff whats weak nerf whats strong aspect, nothing on her kit screams weak other than her lane phase, where she has long cooldowns. She's meant to be weak in the early game, and strong in the mid to late game. I'm not asking for that to be nerfed, what i'm asking to be nerfed is what is strong, which is the E's AD ratio shield. A self generated shield that also is a dash with scaling based on bonus AD being 1 to 1 ratio just seems a little out of hand. Any other type of castable shield doesn't particularly run on a high damage stat ratio (AP shields are somewhat high in certain cases, but for some supports, its due to the lack of AP they would have) or possesses a low cooldown such as Riven's. The shield currently allows her to build full on damage with one or two defensive items (Mercs and Maw for AP, Tabis and GA for AD, and Mercs or Tabis with GA for mixed/core) and not feel threatened at all, where as any counter or damage dealer that goes against her has to either be able to burst her to death before she kills them or be generally scared of her for the rest of the match because their damage just doesn't stick.

Finally, if you think i'm posting this because i'm salty that I "can't" beat Riven or can't play her, then go ahead and think that, as that is far from the actual reason for the post. I really have no interest in playing Riven, nor do I have the speed and skills for her (personal issue), even though her kit is fun to play. I had Riven as my most killed last year at 999 kills (I find it funny to this day that I killed that many), so i'm sure i'm able to, ya know, beat her. I do hope people take this post seriously, and if people have better ideas or suggestions to tackle this issue, by any means comment below.

EDIT: Looked over the data to make sure all was correct, and realized I was using the wrong stat for the counter issue, her counters currently sit roughly 50 55% atm. The thing I was looking at was general winrate of the champion possibly. I removed the sentences about that since they now were not needed and were incorrect.
