Dark Matter Campaign is a good repeated campaign, but it needs some changes to keep interest in it.

A good way to do this, would be to allow one stat to be locked and then continue to work on others, for instance if you have a piece of gear with +2 refresh you could lock that stat and then try to get better stats in the other slots.

This would make a piece of gear that is currently capped out and unable to be changed anymore, as a path of progression again.
