Is 5* duped Quake worth r4?

Is 5* duped Quake worth r4? I mean her damage output changes significantly with rankup or just makes a slight difference.

Rank 5 worthy

Even R5 eventually, I'd say.

R4 quake is worth even unduped she is my best bosskiller

If you can use her very good, then yes she's worth r5. If not, then no.

So its safe to assume that her damage output significantly increases with her rankup. Right?

Easily r5 worthy, 2nd best in the game imo
