Most of these characters weren't together as part of a group, but were part of The Avengers at various times. Triathlon and Silverclaw were introduced during the Busiek/Perez run. Whether you like those characters or not, it was definitely not a time where "everyone was skipping The Avengers". Dr. Druid was involved in three of the best Avengers stories IMO...Masters of Evil takeover of Avengers mansion....The Olympian Gods vs The Avengers, and the Super Adaptoid revenge story. All of these were excellent stories with some great iconic moments. I will give you that Druid was involved in some of the team's low points, but The Avengers isn't just "The Big Three". It never has been.
