I expect Bendis just didn't want to use Moondragon in GOTG. During AvX, the Avengers were at a tactical disadvantage due to the X-Men having lots of telepaths, and rather than having them call in Moondragon, Bendis retconned in a prior Moondragon/Hawkeye hookup and had Clint say he didn't want the team to use her due to awkwardness.

That's going to a lot of trouble to not use Moondragon.

I guess maybe he was contriving the situation for plot reasons. I only read a preview of that issue, which included the scene in question, so I don't know where the story went from there.

If I were going to have an Avenger insist that Moondragon not be involved, it would be Thor.
