I don't mind regression in some cases, like Gargan being Scorpy again or when Kingsley becomes ol' Hobby again.
I wouldn't mind seeing Phil progress into a fallen hero/villain after Kingsley dethrones him, should he survive it. If Roddy is Winkler Processing Phil, it would be cool for him to eventually fight it off and try to make up fors his sins as the Hobgoblin. Remember, he's supposed to be a Peter Parker clone now. He's lacking a personal tradgedy or something to set him on the right path, and this could be it.
As for the Jackal's return soon, I hope he's more like he was when Gerry Conway wrote and when Ross Andru drew him. I hated the 90's Jackal. In fact, I think 90's Jackal was a clone. It's the only way him wanting to replace the human population with clones makes any sense during "Maximum Clonage".
A very defective clone would be a great explanation. Well who knows what Phil's personal tragedy will be. Will he murder his own Uncle Ben? I doubt that since he's not getting any face time like Marla.
His relationship with Norah? That's too meh and that teaser caption should have him being kneed in the goblin nads by her. Or is his tragedy the overall mess he'll make his life.
The only way I can see Slott redeeming himself and make me full on recant is after the fall something like this happens. That after a massive battle Phil is exposed and hauled into a cell.
After a night he gets a visitor, Kingsley. Roderick congratulates him for his career as the Hobgoblin but then berates him for letting things get too personal. That in the end, Phil broke the rule Kingsley abides by: only look out for #1 and screw everyone else. Phil then muses this is just his form of sanity playing tricks on him to which Roderick states he is far from a ghost and is very real grabbing Phil by the throat. Cue the, "Your dead and I killed you." cliche.
Kingsley then states that yes Phil did kill a Hobgoblin, but not him, the Secret War Hobgoblin. He then goes on stating that during his "retirement" Roddy learned of another person bearing the Hobgoblin name and made him fully into his pawn. A being who could test the waters of New York for him. Though Roddy admits being dis-satisfied at the dupe dying, he admits what Phil did worked out better than he had ever hoped. The world believes him dead, whatever Phil does to the underworld causes a crack, and all through this Kingsley has amassed just enough criminal power to become a major player. Phil then scoffs at the fact he'll now end up as Macendale to which Roderick wags his finger stating he won't it would be too personal to just murder him. So what fate does Kingsley give Phil? He condemns Phil to live and be consumed by his madness and sins. With that Roddy bids him adieu and cue the real grand Hobgoblin story to tell down the line.
