So many of us spend ages playing mmos with our wives or gfs. How awesum wouldn't it be if you were to get a group buff or a set of group buffs that grow in strengh as the two ( or more ) of you adventure in the far off lands ? Your group ( you and your regular companions ) grow so much stronger from playing together that every bit of xp gained as a group should move towards strengthening that bond. You could event assign group stats on leveling the group bond. I would have luved that.
