This is what I would've preferred to see: Claire/Tripp/Haley triangle where Claire is just scheming and not attempting to murder people. Haley does find out Melinda is her mom and we get a backstory for both.
JJ/Haley are just friends both realizing its a bad idea to date being coworkers and all(what do you know an organic obstacle no suicide attempt or immigration storyline here) maybe be a couple down the line if it works.
JJ would be in the middle of his parents story as despite his age he fits better with the vets than the younger set. Eve is driven to make Ben's life a living hell as soon as she returns to town and JJ is an unlikely ally in this quest. Eve still torments J&J but still has a purpose beyond that(making Ben suffer). While Jennifer/Eve battle for Jack's soul and yes Eve does marry Jack in my version of events but its a MOC for both. Jack is drawn to Jennifer and his past going down memory lane while Jennifer tries to find out about his missing years while Eve is consumed with revenge vs Ben right along with JJ and they end up reigniting their affair with Jack walking in on it this time.
Claire isn't crazy. Eve has a story that makes sense with her, Ben is less neutered from his SK persona, Haley isn't forcefed on the audience, Tripp might have something to do, JJ gets an edge back and is a bit more messy and shady again, Jennifer is actually involved in her story. Jack has a POV trying to figure out who he is.
Instead we got something else....
