I don't think you understand Wing Tyun at all. Wing Tyun encourages change and development and it is expected for a technician grade to theorise and propose improvements to the system. Wing Tyun is anything but traditional. I certainly do not blindly follow my instructors at all, nor are we expected to, everything taught is demonstrated practically against realistic situations and trained applied against an opponent. Wing Tyun is not like many other Kung Fu systems where lots of 'unnecessary' flamboyant movements have been added, it is based on minimum effort, maximum effect - it is not 'pretty'. I will refrain from going on, but i suggest you read up a little more on the system. I'm not saying it's better or worse than any other system, just that i think you have misunderstood it.
