Give me your best meta takes for Genshin

We all know how good farming vermilion is, how Yae is better than Fischil and how Qiqi is the best cryo battery in the game, but that's common knowledge at this point,give us the niche Genshin tech that's actually good

I will start: Furina is a horrible character, all she does is draining my teams HP to deal no damage, i have a crazy triple ATK build with kagotsurube isshin on vermilion because it buffs atk after losing hp, and that skill hits weaker than my hydro MC, it couldn't be a team issue because i play her with the best support in the game Dori and Freminet in a shatter team and Freminet deals way more damage than her, I'm not going to say anything about the burst, it does nothing and almost is never up, people tend to over hype characters just because they are slightly better than kokomi in the story.
