Yeah, it bears noting I haven't actually READ much of anything the characters were in since McDuffie's pretty-good FF run. (I would also add that Jason Aaron did a pretty good job with them in his Secret Invasion tie-in.) But yeah the marriage DID feel forced and abrupt -- but then again, so did Peter and MJ, and that managed to hold for what, 25 years before being retconned by Satan?
I DO think that combining the X-Men and Avengers into a single team is a solution to the biggest hurdle, that Storm is on a US-based superhero team while married to an African king, and that we haven't necessarily heard the last of it. But I'm not going to miss it either, particularly inasmuch as I'm not buying Avengers or X-books.
I think Priest did a pretty good job with the two of them in Sturm und Drang -- my favorite single arc in his entire excellent BP run --, but honestly Storm was the LEAST interesting guest star in that story; I was much more interested in his exploration of the international relations between Wakanda, Atlantis, Genosha, and Latveria.
