Anything to increase intensity and shock the muscle is good. You just need to know when to do it. Some lifters do drop sets and rest pauses far too much. I think for certain exercises and on the last set is perfect. Although sometimes it's feels good going in and just crushing a muscle
Good post. I have been guilty of overdoing rest pauses and forced reps in the past. It's important to know when to add them in. Too much just goes against recovery.
