This complaint always bothered me, in particular about the dropkick. Maybe it's because of my own background, but how I think of it is like this: hit a punching bag for a while. Then, occasionally miss. Instead of landing the big straight, purposefully throw it so you miss. What happens? You waste a lot more energy and are more likely to injure yourself (at least if you're throwing as hard as possible). To me, the dropkick vs. the missed dropkick are the same thing. Landing a splash vs. missing a splash is a similar concept, albeit there it's a guy being softer to land on than the supposedly hard mat.
