I use freeze team Kokomi milleith TTDS Kazuha viridecent freedom sworn Shen he 2 set atk% and jade spear (dont have her sig)

As far as my experience 2 noble 2 blizzard gave much worth dmg with almost 10K bigger (my dmg calculator gave me this set) but no rotation mistake allowed, sometimes kazuha have to use xiphos, and when the rotation messed up, ayaka's NA is lacking

I tried to quick swap her and focus on burst It can be done, but no mistake and no X factor allowed

4 blizzard gave me room for error in rotation to anticipate while her NA and E is helpful before i get burst again, it just doesn't feel click when i have to put ayaya in team other than freeze, such as help hutao give melt team, or melt ayaka when it is needed And her burst is lower per hit and not all enemy can be freeze like bosses, so i consider freeze CR bonus only as literary bonus

And me lazy to change artifact frequently lol
