I noticed after playing cooperative missions for awhile that there is room for a few improvements to the Compass or Radar, however you want to term it.
-It would be nice to have arrows for your teammates if they, or you, stray too far away from the group and need to get back to them fast.
-If your party members could be represented by colors other than the default green on the radar, then that would be a bonus as well.
The only reason why I am mentioning this is because sometimes when you are paired with people who do not have a clue as to where they are going often become seperated from the main group and finding them after they walk off and do not return calls to return or requests of the current area they are in usually fail miserably. A system in which members of your party in towns and wilderness areas are distinguishable by a color system would be a nice addition to this otherwise very good game.

BTW like the mini map idea!
