There shouldn't be any significant wing drop with the 172 during power on or power off stalls. That's a rudder issue. Reduce power if necessary during the recovery, but it shouldn't be necessary.
Pitch change shouldn't be dramatic, either. Many instructors wrongfully make it so, frightening their students, but recovery is as simple as a few ounces less back pressure on the yoke, and a degree change in pitch. If an instructor is introducing the airplane or the maneuver with dramatic changes, the instructor is doing you a disservice.
