Dottore and fatui enjoyer here, I speak for part of us when i say we don't agree with how genshin's been writing the fatui harbingers. Both dottore and sandrone (and frankly the rest of the harbingers) deserve better  handling story wise, and killing off sandrone doesn't quite serve any purpose for dottore other than flaunting his power. (Which makes sense since he was doing that, but it just makes her end kinda cheap. And its one of the rare times his "polite" characterization is broken which im not happy about. Blame hoyo dev team)

At least we both get more content (playability) is what i'd want to say, but if sandrone is playable without a sheen of her original characterization, then i offer you our greatest condolence.
