I Like Yuumi A Lot, But...
there are two things I find kind of painful to work with. The first is the base health. It's just suuuuper low, so low. It's the second lowest health in the game at 430 starting health. Starting health of 490ish, which is where Lux is at, would make a huge difference. It leaves people with a feeling of needing to be attached early game, which leaves the ADC feeling like they are alone. A bump into normal low health range instead of Ultra Low Health Range would help alleviate this.
The other thing is the detach. Just feels kind of janky. I understand it can't be a dash out, too OP, but please make detach direction choosable and instant.
Otherwise, I been having fun with Yuumi, I dig her.
