But, since they're known as being Magneto's children, it's Marvel who are "needlessly" using them and are "handicapped". >.>
I realize those characters can be worked into the script, but it's a matter of whether the time is right and if it makes sense. People don't think about those things. Why would they have Ms. Marvel be in Avengers 2 before anything Kree and Captain Marvel related have been introduced? Why would they have Ant-Man and Wasp in Avengers 2 right before their origin movie? And why would they have those things together? Those are big characters and they need time to be introduced less you waste their potential. It's just not time for them and people need to be patient about it. Not to mention the Maximoffs joined the Avengers before any of those characters sans Wasp and Ant-Man and were a part of only the second incarnation of the Avengers roster, so from even that perspective it makes sense to have them in the sequel.
Fox having to alter their origin won't be a huge deal. It's not hard to do when they're so easily adaptable to the X-Men universe.
I do think about things like that, lol. How do we know nothing Kree related and Captain Marvel won't be introduced before TA2? There is a strong chance of that with the GOTG movie coming out, and Carol even has a chance of being in that movie before she gets her powers.
And about the Ant-Man and Wasp thing, we don't know if Ant-Man will play like an origin movie or not. It's possible that TA2 could introduce them, and Ant-Man could continue their story. Order of appearances really don't matter in the movies at this point, because if they were going by that logic, Ant-Man and Wasp would have been in the first movie.
