That part you quoted really doesn't make sense. Sounds as if hes implying Sol isnt a debuffer. One of the main reasons of gettting Sol is for her rare cframe atk down debuff and until they patch the debuff cap, her value only increases.

I'm not sure about several of the kamihimes hes mentioned either, will those even be out for the first ticket? Though using Amaterasu as an example of a kamihime with 3 good skills, I'm not sure what to think. (Her only real use is her 20/20 atkdef down.)
