While we were progressing Manipulator (Savage), my melee buddy (MNK main) went in on NIN with mostly Law gear to see what would happen, and we ended up with similar raid DPS. This was after 3.07. So, he stayed MNK because that fight is Some HP Necessary and is more comfortable with the job, but yeah, that was a very practical demonstration of how far behind a DRG/MNK is compared to DRG/NIN.
