She's a unit that seems to fit PvP more than PvE, and she doesn't struggle with AP as much as it seems, even without xiza bells.
It takes some effort/resources to highlight her strengths and team setup, so she's not super flexible. Understandably, she's closer to A+ than she is to SS. Will be updated as more results show up after more people get her to 120.
this is why she's not ss.
she needs specific vc, get killed so easily by shooter, can't work in rainbow team unlike the other ss.
so far I only lost to light com if yuna revived her.
