Ehhhhhhhhhhhhhh. When I think Avengers I think of the heavy hitters, the most iconic, and a couple underdogs that deserve the chance. Miles, Kamala, and Sam don't really fit any of that to me. Whor does fit that role but her comic has not won me over. I don't like her as a character but who knows what Waid can do with her.
And then there's the diversity. There's no way to deny that's the main reason this roster is the way it is.
