To get back on the proper subject, I would REALLY love it if they would just expand the Duty Recorder to ALL party related duties, whether it be a dungeon, Trial (normal or EX), or raid (Normal or Savage) Even stuff such as PotD and HoH should be included (if not all of it, maybe just the boss floors)
There are certain things that you can do in the Duty Recorder that you can't do just by recording your footage with a recording program, such as adjust camera angles and such.

IMO, however, if they really aren't gonna do anything more with Duty Recorder, then they should just remove it alltogether.
