She would be proccing most of them but your alternative team setups would have equally little crit across that team slot
Baizhu, Yaoyao, and Barbara all essentially have 0 crit
Siggy feels like shit if she has to build HP, em, ER, and crit too

If it's super weighted towards crit and not em you would probably run double prototype amber dps/subdps characters instead of a healer or something
