I've tried out her at immortal repertoire and I can say she'll probably be the best electro DPS in the game for now.
I used Zhiliu&Fushu&Randy to test this out. I put Randy only to give him the new w.i. morale wedge and fushu's combat partner skill. He'll be replaced by Yuming because Yuming will be a much much much much and much better support for Zhiliu.
She already gains %15 morale boost from unlocking her skills. A +5 purple blaze*morale gives %12 morale, and a purple prime*morale gives %18. The new electro wings*inspo*morale gives 36% Morale, which is insane! And this only applies to +5. Once this wedge will be maxed out, it'll give 66% morale.
So, with only purple morale wedges and +5 w.i morale she gains 81% morale.
In addition to that, Yuming gives 15% morale when he's a combat partner. So, that means Zhiliu will have almost 100% morale. And will exceed 100% if you have 2 +5 purple blaze*morale
That's really crazy.
However, she has a small issue: her skills are so slow and delayed. And she's really skill-depended. She's too much depended on her skills, and that's not really the issue. Lady Nifle, for example, is another skill-depended character. Okay, her playstyle completely changes at i6. But even before i6, her skills don't feel slow/delayed compared to Zhiliu's. More importantly, I enjoyed playing Lady Nifle even before her i6.
Zhiliu's entire gameplay is based on her skills and she can't move during any of her skills, only be able to move after a bit delay of casting her skills. Don't get me wrong but I don't enjoy while playing her. I love her design and to me, she's really an interesting character in the story. But her gameplay... I didn't like it at all.
But yes, she's definitely strong even with my low-invested wedges.

I hope they don't make yuming skill animation like her 🤞

so her skill animation is long and and you can not cancel it
