What does Feferi add?

On my 8th or 9th reread of homestuck rn and over the years I always wondered what her character was supposed to add? like plenty of characters are under-represented the homestucks run, but of the main trolls everyone does something to forward the plot but her, unless you count eridan and sollux fighting over her? she get almost 0 screentime, feels like she got kinda snubbed. Am I just illiterate and have missed something everytime I've read since 2014ish? Not attacking her character jus curious.
