She's a pretty great party member, especially with a mage focused group since Reis' Wind restores MP to the whole party (including Freya's own MP, meaning she can cast it indefinitely) and she's pretty much a beast of a party member. While she can't hit as hard as her job classes previous incarnations, she makes up for it with her OP skill pool.

Also, if you steal the Holy Lance from the Ark Airship boss battle, she becomes way more powerful than the rest of the party since it's like her second or third best weapon whereas the rest of the party has a way to go to get theirs.
