So much truth here. I, pretty much, ignored the interpretation of this author. You've captured all of my sticking points with the article. The author has put Ororo in so many boxes, as well as labeled her in ways, as you pointed, that haven't been established in the comics. Until it's written that she is High Priestess of Krakoa, then she isn't. Until she is written as being a militant anti-human mutant supremacist, then she isn't. If she is eventually written that way, it would be a gross mischaracterization that would make me sick to my stomach.
There is so much to the Ororo character that could make for a great series, mini or otherwise, that has nothing to do with T'Challa and Wakanda. At the same time, I don't see any reason why that aspect of her life wouldn't be showcased in a solo. But her relationship with T'Challa is only one aspect of her life, just as her being a mutant, a woman, goddess, etc, are all aspects of who she is and could be explored in a solo. I really do think Coates would've done a great job with a Storm solo. Slow pacing (LOL) but still a great job. I do think he "gets" her as a character and has put in the work to read her backstories.
