My wifes 99 mystique was how you described the rears. She also isn't one to ride the brakes MTX car. There never seemed to be any drag when I drove it either. I talked with a mechanic and he said he has seen a few cars with rear discs that they wore out before the fronts. After full replacement of pads and rotors I haven't seen anything out of the ordinary on the rears. I just did my SVTs brakes and they were in much better shape but most of there life was highway.
