The changes you made (changing her resource to Flow, making her transformation more frequent, having Harrier deal damage based on the target's current health) would make Quinn a much better top laner, but doesn't really answer Quinn's core problems: what's her identity? What does it mean for her to be in ranged form, or in melee form? Why would she want to sacrifice her range advantage in an average trade?

That aside, there's the issue of applying the Gnar model to Quinn in the first place: building up from one form to another is fitting for Gnar because his two forms are completely different, and have entirely independent strengths and weaknesses that allow him to be two champions at once at the cost of reliability. That same model doesn't really work for Quinn when she does the same thing in both melee and ranged form. Additionally, the reason Quinn has such a ridiculously high cooldown on Tag Team/Skystrike right now is because of how snowbally the ability makes her: if she gets a lead on her opponent, she can easily turn to bird form, chase them down and execute them, which is why she shouldn't be able to do it all the time. If she were able to do the same thing every 60 seconds from level 1, with the kit she has she'd snowball super-hard at the first lead she'd get.

You might be onto something, but I think you need to take your rework down a little further: is Quinn a marksman? Is she an assassin, a ranged bruiser? Can she be two different archetypes at once? What is she good at in one form that she isn't at the other? What is the purpose of each form?
