Most amazingly (to myself anyway) was the general assumption being made, that any effective application of a joint-lock was made (either) by luck, or by accident.
For me, this represents the opinion of someone who only has limited experience, or limited knowledge in regards to the use and/or application of joint-locks. A “book” author (who was being quoted numerous times in the article I read) made the most telling of the assumptions.
A lot of what they presented for an “argument” (against) their use and/or applicability, is based around the (presumed) complexity of the technique's application. If it were a newly learned technique, this may very well be a relevant factor, but for the experienced practitioner, performing a repeatedly practiced technique, not so much.
