Juliette wasn't a fully formed character until Adalind started targeting those closest to Nick after Marie's death. For half of the first season she was just the girlfriend he went home to, a sounding board for the new frustrations of work as a cop developing into a Grimm, plus a human target that added more angst to the main character. Juliette felt more real rejecting Nick's proposal in the first episode than for the subsequent fifteen or so episodes thereafter. She came alive once more when Nick decided to tell her the truth about what had been happening, then enter an embittered, vengeful, powerless Adalind.....
In S1, Adalind had far less screen time than Juliette but she had a storyline of being Nick's antagonist. They started to develop Juliette from S2 onwards but it was about how to bring her fully into Nick's world. While Adalind's story was still fairly independent of Nick, the writers still found ways to have those two cross paths despite it being unnecessary (Kelly bringing her back to Portland with baby Diana and eventually her second pregnancy) and that's because Nick was the central figures that the other characters would/had to revolve around. A consequence of this type of storytelling of creating a world around the title characteras opposed to creating a character within a larger world that spans beyond him/her. It was Nick's story and every either fits around him or they are expendable.
They messed up with Juliette and Eve was a band-aid on a gaping wound in terms of the narrative but I think it's really more the writers keeping the actress probably because of contractual issues and the writers penchant for keeping people around because they wanted to and in some cases to the detriment of the show. It meant whatever they wrote as a result didn't feel organic to story. The only time someone left the show was because the actors had obligations outside of the show (Erik and Kelly)
