I want Lulu on the show as a character who reminds us through behavior that she's a Spencer, and why she values what she values. For example, a conversation with Laura where she says "It was hard for me to grow up into my teenage years without a real family under one roof, and I want that more than anything now. That's why I've struggled with Valentin over custody of Charlotte, and why it's so hard being without Dante."
Then I would empathize with Lulu, that she had more or less reached a place in her life where she had a happy family life and then it was gone, versus acting like he just has some minor mental health issues and went away because he wanted to be alone instead of being a family man. Lulu should have some in-depth conversations with her mom about what they both missed out on when she was growing up such as time with each other and with her brothers, rather than the idiotic, foundation-less (given her background) "I'm a superstar professional reporter" storyline. Lulu should have a career too, but one that makes sense for who she is. I believe Elizabeth is a nurse because she has a compassionate personality for people who are suffering, and her grandparents were well known at GH. I believe Maxie is a fashion editor because she's been into fashion since she was a teenager and she has the type of scheming personality that can be beneficial in the publishing world. On the other hand, I don't think I recall Lulu ever even reading a newspaper or magazine before she got the job with Peter.
