Riven Resource Idea

I have noticed while playing, that the majority of people playing Riven, simply spam her abilities, and hope something good happens. Since she has a ton of damage along with a highly forgiving shield, this tends to work out in their favor. My idea is for a resource (that works with her intended playstyle) that she uses to cast her abilities. The resource is called Vigor.

Riven spawns with her max 100 Vigor. Whenever Riven autoattacks, she gains 10 Vigor; if the attack is empowered by Runic Blade, she gains 20.

Broken Wings: Upon each activation of Broken Wings, 20 Vigor is depleted.

Ki Burst: cost 20 Vigor

Valor: cost 20 Vigor

Blade of the Exile: No Cost

Well, thank you for reading my idea for a passive that would make Riven more aligned to her intended playstyle, rather than a highly forgiving faceroll champion.
