These are the key words here, there is content available, and a lot of it, you just don't want to do it.
Our static plays through content slow and steadily, we learn it in our own pace and never really run out of anything to do. If we don't want to run AS or Thordan, we help others with early content like FCoB or help them get ponies. Sure, it's not shiny new content, but we have fun doing it because we're doing it together.
If you look past trying to do everything that's new in the shortest amount of time, there's plenty to do. Most people just don't want to do it.
