I can empathize somewhat with that view. We'd danced previous to AT for many years and had a concept of axis, frame, posture, position, height, balance, lead/follow, etc, but AT re-engineered that. At one extreme (IMHO not good) we had an over-emphasis on technique: walking, disociating, pivoting, etc. It didn't mean a lot then. We wanted to learn 'steps' to be able to dance. Not to wait 2-3 years to develop the technique. At another extreme (a brief, unsuccessful, foray into ballroom) we'd learned sequences of steps.My experience in group lessons is that the focus is on steps, not what my AT teacher calls dance fundamentals (axis, frame, posture, and balance.) Frame isn't corrected.
So, we learned some basics (from a ballroom instructor who did actually understand social AT and the differences). Then we did workshops, group lessons, privates, courses, etc, and learned more complicated steps and how to lead/follow them - and some 'technique' to make those better. We're not past learning how those moves can be combined in different ways, or even new moves, but the emphasis now is on doing them 'elegantly', for want of a better descriptor, getting an appropriate lead, and musicality in applying them.
In fact we were recently commenting that one of our teachers, in group lessons, tends to emphasize steps, but will add information on position, posture, timing, etc only if asked. Another teacher tends to overemphasize the technique for some simple sequence, but to the detriment of keeping interest in the group.
Fortunately we have other teachers, or more 'coaches', to whom we'd go for detailed technical assistance, correction and general presentation in an intensive way.
I'm inclined to think that you don't know what you lack in technique until you have sufficient vocabulary and/or need. And I'd guess that the old apprenticeship method of learning managed that in its era; but that's just inappropriate at our age and in our society.
As an aside, someone who started learning AT around the same time used to describe sacadas as 'the leg stick thing' (and still does); I'm thinking high or low sacada (and who might we hit); follower side step or fwd; which leg do I stand on for this; do I pivot; my foot position relative to follower, leg extension and part of leg (a deep sacada?), our embrace, etc, etc
