Is Haze really a crutch?

Was playing the other day and got called a Haze crutch, from a doorman player nonetheless. I’m still pretty new so I’m playing who seems fun and Haze seems fun to me. All the “play who you enjoy” and “don’t listen to haters” aside, is she really a crutch? I’ve seen some complaints around her being an ult bot which I do understand and agree with to some extent. However I think she requires better aim than normal to be able to stack fixation and having good target prio and positioning is more important to be able to get good ults. Might just be me coping as someone who plays Haze tho.
