Kayle's passive and her design.
I'm not gonna talk about her armor (I do wish her helm was a toggle though). But mostly about her color scheme.
To be honest, I feel like achieving her second point in R is a downgrade to her color scheme. Her colors that may serve as iconography for what she represents are washed out in a dull "gold" color. I like the white gold and wine red (For purity, prestige, and power). We already see 6 wings, why do we need to wash her colors out?
By level 16, now her beautiful sky colored wings that emit flames are just a glowy yellow, along with the rest of her body, there's less distinguishment, I feel like if she was allowed to evolve further she would end up being a banana. Thoughts? I'd like it if her armor and wings remained their respective colors honestly. I love the firey look the wings take on, as if the sky itself is burning.
