Seems like when the Avengers as a group guest-star in a title, it's typically the characters you'd think of as the "main" Avengers (i.e. Cap, Thor), and never the more peripheral characters (i.e. Cannonball or Shang-Chi). Any reason for that? I get that you'd want some recognizable characters, but why not include one or two characters who are full-fledged Avengers but seem to barely show up even in their own team's title? After all, they're just as much members of the Avengers.
