I think a big part of the problem comes from practicing the performance of the forms in a way that's detached from any understanding of their application. Given the fact that a lot of people don't really visualize their MA's form sets as the documentation of real fighting techniques, but rather as some kind of martial folk dance, that's not surprising. But I think it leads to exactly the problem noted in the OP. For the people I'm talking about, form takes precedence over function, because they don't have a clear idea of what the function served by forms really is.
Once I started learning how to do the kind of analysis of form application that's standardly labeled bunkai, I started practicing forms in a way that corresponds to the street-practical use I envisage for them. So a retraction/punch movement for me represents a trapping and pulling inward of an attacker's limb, and the punch is the payoff (which may be a palm-heel strike or any number of others things), prepared for by the hikite-movement that's typically labeled 'chambering'. And when I practice the form, that's what I visualize happening. When I do a pivot, I am visualizing a throw, and moving as though I actually were holding onto someone and throwing themĀbecause in a lot of the TKD colored belt forms I do, the pivot makes most sense as part of the previous combat scenario (not a mirror-imaging of that scenario to the other side), where the pivot corresponds to the total unbalancing and downing of an already damaged antagonist. By practicing forms that way, and visualizing them in terms of their combat content, I find much more satisfaction and interest in them than if they were nothing more than some sterile set-piece which you had to get just right because... well, as the joke bumper sticker has it, 'there's no reason for it, it's just our policy'.
When I teach beginners, I try to get them to understand, even at a very elementary level, that forms have combat content, and that when you carry out a movement in a form, you need to see your attacker, see the attack coming in, see your defense unfolding in real action. It's never too early to start learning that kind of visualization, even if the techs are still quite basic. As the Brits like to say, begin as you mean to go on...
