Honestly, OP cited competing in GP and Children’s Ponies at the same show in support of a rule change? Really? That kind of sensationalism doesnt help the argument.
People do what some refer to as 'slumming", seeking out lesser competition in order to win and amass points or qualify for some Finals or other. To me that’s poor sportsmanship but if it’s within the rules? That’s on them, not going to waste my emotional energy on them. But WEF is not "lesser competition in any way, shape or form.
This was not “slumming”. It’s the biggest, most competitive and probably easily most expensive show in the country to attend. The best of the best are there, particularly in the Big Eq AND that 15-17 age group Eq. (As noted upthread, there is no "Open Eq and this level show). Kids are trying to tune up and qualify for Finals and Indoors and they are going to go in every class they are eligible for. You need to expect riding against the best of the best or seek a smaller sandbox. Ocala for one, Gulfport and Pensacola is also getting popular as a suitable alternative. No knock on these venues quality wise, they are very well run and competitive, just more realistic and a little to a whole lot less expensive.
Thinking the trainer here told the kids they very likely would be in over their heads at a WEF and need to appreciate the opportunity as a (very expensive) learning experience. But either kid or parent was nursing a pipe dream and couldn’t handle the truth. IMO facing a more experienced and skilled competitor is not graft or corruption.
Nothing to do with cross entry legalities but WEF is a huge marketplace. BN European and SA trainer/riders bring well started young horses to sell, US trainers import sale prospects directly to WEF to take advantage of the one stop marketing, show experience and on site vet availability. You have to expect to see these prospects any class they feel will be beneficial under a variety of qualified riders, including younger ones seeking saddle time to work their way up the ranks.
Im a small fish too. Could have gone to WEF, maybe gotten a pastel or two in the Adults one year. Passed the 10k tag, flew down without the horse and had a wonderful learning experience hacked a few, trail ride around the neighborhood, took a few lessons. I rode in the schooling ring with the BNT/Rs. Recommend that experience for most if you don’t want to face that level of competition.
