I personally think it's two fold (though again, it's just my guess).
Firstly, I think there's a desire to play with the familiar toys in the toy box that the writers themselves grew up reading about. The Avengers, the Fantastic Four, Spider-Man, etc. And they're all in New York. I think that's a reflection of the fan buy in every comic book writer coming through.
But secondly, I think for characters like T'Challa and Thor and Namor there's simply a greater vulnerability for those characters outside their realms. And I think most writers want that. If you wanna do a Kraven vs Black Panther story, odds are you don't wanna do that in Wakanda because poor Kraven in theory should need to go through the entire freaking Wakandan army to get to T'Challa. Against most threats T'Challa shouldn't even have to do anything when he's there. Have T'Challa by himself outside of Wakanda, and he becomes far more beatable. Which for story purposes is often a good thing. Occasionally you can have someone like a Doom go into Wakanda and kick behind, but that's not necessarily something you want happening all the time.
Of course, that's all just conjecture on my part. Take it for what it's worth (which isn't much).
