Johns continues to write Diana as he wants.
She's no longer the "bloodthirsty warrior" of a few years ago because it has already served its purpose (Trinity War) but she's still the "confused girl" that doesn't know how relationships and feelings work because she doesn't have a life outside the JL (do you remember that?).
It seems that now Johns is developing the next stage of the plot points introduced in the early years of the series. So expect that Diana's "complicated love life" and her behavior will lead to another event like Trinity War like the last time.
Argus and Trevor against a fractured JL and Superman. And all 'cause of her. Again.
