Stun support advice

Alright so i just pulled on Nangong Yu's banner and got her M0 and i'm pairing her with the Ice-Jade Teapot W-Engine for pure impact and daze generation. I'm not using her within an anomaly framework, her sole purpose is to be a premium dedicated on-field stun support for my M1 Sigrid. I couldn't put up with my shitty clunky and slow feeling M0 Koleda anymore so i dipped into my pull reserves to get her. I don't at all regret this as my account hilariously lacking premium stun support. What are your thoughts on how i'm using her?
