Observation - It is really hard to participate to the end of the FA and not have some leftover badges. It might seem inefficient, but it is probably unrealistic to desire full use.
Question - are these unused badges ones that you made a special effort to make, or are they badges that you collected through normal play?
Either way, if this is still a goal, consider making more of an effort, individually or Fellowship-wide, on the badges you were not in excess of.
