Victim/witness often aren't called for preliminary hearings, but they are needed for trials. Reports are not witnesses and can't be cross examined. The testimony is evidence, not the report.
Granted, most people that commit the offense are not likely to push for trial when the cards are against them. Plea deals are more common and nobody has to go to court.
This is a petty offense and will sooner see a dismissal with an uncooperative out of town victim than a subpoena and victim being hauled in against his will.
If plea offers are refused and OP pushes this to trial, and the victim fails to show up and be a victim in court, the matter will be dismissed.
OP, you should discuss with your attorney the potential advantage of refusing to waive time.
