That is such a good point.
I've even read where writers state that "they hate writing Gambit", when this character has the most untapped potential for excellent storytelling. I'm gonna share something chief said... (not totally verbatim, kinda paraphrasing, but you know) "The complexity of his past, his struggles, and how that affected and shaped his morals and beliefs, not only lays the foundation of developing the perfect antihero, but is also an excellent exploration of the human experience and psyche. It's why despite how much this character is ignored and at times shunned by writers, Gambit continues to stand as one of the most popular X-Men. His story in essence, is highly relatable, and should a writer that cares write his narrative, his story would resonate with the reader on a very deep level. Of course, that takes care, love for said character, and real talent to do so..."
It's something many of us discuss a LOT on, and how much Gambit is unrealized as a character. It is something chief discusses with us, and how she really want to realize so many key points of his story and narrative, and bring him to his full potential.
While... this story, our animated narrative has been affected by COPPA and so... certain things had to change drastically, but... with that, the rediscovery of Remy's past, him learning how his environment groomed him, revisiting devastating and torturous moments of his early life, the mistakes he made along the way, rediscovering his role in the Guild, (a horrifying new plot involving another Marvel villain which is, very dark and intense), all while trying to overcome these demons, and realize the person, the hero HE wants to determine for himself, are the elements that she wants to bring home. And, despite how his past shaped him, the msg is, it's up to him to determine his fate and who(what) he becomes.
WOW, someone else (think it was Gripstir, but someone from FB too) mentioned Madripoor and more exploration of that plot. The Guild in general is given a major facelift, with more development of their operations, their mythos, how they employ the mystic arts with combat and their missions, and also, the additions of 4 more Guilds, under various families (with the top Guilds being Thieves and Assassins).
Chief has a very, VERY interesting plot involving Sinister with Gambit's past (and his birth), and the complexity of everything involving Sinister's true intent, the reason for everything he's done, and what drives him. It all centers around Gambit (and Scott to a degree). Due to a MAJOR evlolution that Gambit experiences in the story, the narrative of Sinister's agenda, his interests in the Summers' genetic line, and Gambit's origins, become a big storyline, that is definitely a slow build over time.
Rogue has undergone a lot of facelifting as well. I really like the ideas that are on the table for her character. For one, chief (and others) want to explore her family, over a slow build as well. The current development is Rogue's biological mother turns out to be Mystique, who was thrown out of the home when Rogue was too young to remember (Mystique took the form of a "regular" southern girl to hide from issues). Her father would be abusive, strict and uncaring, and someone mentioned the aunt thing, where he sends Rogue away. She'd run away when "an incident" happened with Cody, revealing she's a Mutant. So domestic circumstances would cause her to runaway from home, wind up in suburban streets, and encounter Mystique in disguise, and then begins her plot with the Brotherhood (btw chief wants to do a limited mini-arc on the Mutant Brotherhood, and see things from their perspective!)
Rogue would have her story developed in a somewhat slow build, with mysterious bits and pieces, until we get our own "X-Origins: Rogue" which gives us the full narrative, and puts all the pieces together. Also, Rogue get's a very interesting, dark twist to come much later into her adulthood, in which she'd become an antihero in her own right... and how it was actually a fateful thing to happen for her. Its a very complex, and even touching plot that's better than most of what I've read of from canon.
Gripstir again, I believe, or Purplevit, told me that they want for the narrative to have them bond over being orphans who was thrown around by fate, used and abused, and feared of due to their mutations, near verbatim to what you're saying.
And Rogue won't only deal with the Mutant Brotherhood in her past, but... down the line as well, which becomes a very important plot
