Yea, I remember Paquin saying she wanted to play a Rogue closer to her comic counterpart. Unfortunately that was never a priority for the directors, sadly. At least this makes it very likely Disney will explore this aspect of Rogue, since casual audiences are not familiar with powerhouse or villain Rogue. If the superhero movie franchise doesn't kill itself by the time we get there... the over saturation and bad to mid quality of the recent movies has really hurt people's trust in the genre.
Yep Rogue was still occasionally treated like an outsider at times up until the 90s. Ororo showed her trust by letting Rogue borrow her powers, but she and Betsy had no tolerance for Rogue's outbursts regarding hating having to share her body with the mental ghost of Carol. They knew it wasn't really Carol either, just the ghost of her memories, so the lack of sympathy from this for a teenager raised by terrorists was a bit a much at times.
(though to be fair, Rogue did try to kill her)
Low-key Betsy felt like she preferred the Carol persona to Rogue. Going out on coffee dates with her even!
Howard writing them as BFFs in Excalibur felt so weird because of this, Claremont wrote them as frenemies or a younger sister annoying her older sister most of the time.
Though their relationship did seem to improve from the 90s onwards, as Rogue matured. Rogue also was the one to avenge Betsy after Vargas killed her I suppose.
