Character Groups and associated Cecil's Tasks

One of each I guess.

This is exactly my point, I think it is less. E.g. Homer is both a Dimwit and a Glutton. Since Cecil only gives one task at a time, there is no need to keep another Dimwit (or Glutton) free.

So I'm looking for the best combination of characters that are part of multiple groups.
