I have made the tier adjustments and removed the matches which used her 9-A key.
Although, there is one more thing which is bothering me. Look at her durability rating:
"at least
Small Building level+ with her prosthetic metal arms, possibly
higher (Was able to
deflect an explosio"
Except when you open that link and view the feat, you'll see that she just deflected the projectile before it exploded. Even though the explosion happened close to her, but it did not happen on her prosthetic metal arms, neither did she "deflect the explosion".
