My take on what Quinn could have been
Quinn's remake I think has proven to be quite a rollercoaster. Super toxic in some areas and super weak in others. I feel like she'll be just as difficult to balance as she was before.
First off, make R a regular toggle. I say give it a 6 second CD like Jayce. Nerf the AS/MS she used to get to levels for a normal toggle. Remove skystrike.
Q (Quinn) - Does whatever amount of damage, marks first target hit as vulnerable. CD reduced by killing units Q (Valor) - Does same amount of damage, does not mark first target his as vulnerable. Instead, blinds first champion hit. CD is not reduced by killing units
W - same
E (Quinn) - same E (Valor) - Valor claw's target, reducing movement speed and damage dealt to him for X amount of seconds (does not interrupt)
I don't have numbers made up for this, but I felt like this is a kit that gives her purpose without being too toxic. Right now, her remake is EXTREMELY snowball heavy. Her roam is unbeatable but useless if you're behind. They've made her dueling a lot better with her Q change, but even that adds to her current toxicity. She's just in a very awkward state I think. I know this remake will never be a thing, but I just wish it could have been.
I think this remake does two things. It makes it so Quinn is the waveclear, the teamfighter. Valor is the roamer, the duelist. She can still roam because she does get MS with Valor, but it's not stupid like her current roam. She is forced to duel in melee because that's where all her utility comes from, so she's put to the same level as other melees (so hopefully not a pain in the ass top). It would weaken her bot lane dueling potential, but she's never really been known to be #1 bot laner so I think people could accept that. I think it would open her up to really being able to do whatever role she wants, but she has her limitations where needed.
This idea could be completely stupid and unbalanced, who knows. It was just something that sounded fun to me and I wanted to share with others :).
Edit: I may think of a change for her E. It seems like it could either be useless because she already has blind or completely broken because now she's immune to basically all damage. I don't know. I just wanted her E to be different between Quinn and Valor because I want more incentive to switch forms other than just for blind.
