You think there are any ansillary characters they could promote to main crew to fill out the numbers?
A lot of them are one note characters like Garrett, Leonard, or Magnitude, but other characters like Neal or that guy with the kettle corn, or they could even bring back Vaughn, and they could be given enough depth to work as leads.
Good God NOT VAUGHN! Was so glad when he left Greendale at the end of Season 1.
I hope that they can make the most of their secondary characters, just want them to use them wisely. Hoping that since Pierce is gone and there'll be less Troy that they can develop things between the remaining characters more. Jeff and Abed, Britta and Shirley, Abed and Shirley, Jeff and Change, Britta and Annie, Jeff and Annie, etc.
