r/Lucilla_Mains

I'm thinking of getting Lucilla mainly because I like her as a character, but I neither plan to get her signature weapon nor have hiyuki. I'll use string master as her weapon.

So I'm wondering how good is Lucilla in echo skill teams? Is she as good as qiuyuan or better/worse? And do I use moonlit clouds or the 3 piece set that qiuyuan uses?
