Bendis disintegrated the Avengers in one fell swoop and gradually put bits and parts back together again in a way that suited him. Then Bendis didn't go the traditional way and use the big 3, but took little known characters and this time, introduced reality into addressing how difficult it was to have super powers. It was a slow like treakle pace, and gave us insights into the dynamics of how a power affected a person. There were tamtrums, interesting vs uninteresting bents on people, powerlessness - which had not been part of Avengers culture.
If Dan wanted to do Avengers, he would have to do it like MA again. Take a good mix of characters, and use something like that Infinate Mansion which was inspirational.
