I am seriously wondering who implants this elite feeling in some people who happen to train for upper level dressage. Is it a money thing? However, I was taught to respect all riding styles, all require training, hard work, time, sweat and sometimes tears. And I also learned not to judge something without knowing what to look for and how to do it.
I can assure you, core, straight, engaged and connected is not sole property of dressage(as you all define dressage)
By claiming it is you come across as know it all and snobbish.
