My coach used to dominate dressage on her draft cross in our area (and he jumped great too). I’m talking 18s and 19s in dressage - she’d be 7 or 8 points ahead of second place and far more from the rest in her division, and under different judges too.
Don’t forget it’s not just about the breeding, it’s about the training and riding. Especially here in Ontario and at the lower levels.
I just scribed nearly 8 hours of dressage tests yesterday from EV115 to EV85, sitting beside a licensed Senior judge and Grand Prix rider, and I’m telling you that the “non-fancy-pedigreed” horses who were correctly ridden and showed good training basics were scored higher than the great movers who were not well-ridden. Sure, he appreciated the gorgeous horses, but if the rider couldn’t put in a good test, they weren’t rewarded.
Now obviously if you get the great mover who is ALSO ridden well, they’re going to score high.
I think you need to seriously consider what you are wanting to get out of a possible new horse. Do you want to enjoy yourself safely, regardless of whether you win? Do you only want to win? Do you want to go into debt to finance an expensive horse who might colic or break its leg the day after you get it? None of these answers are wrong - you just need to decide what you really want and what you are willing to pay to get it.
Please don’t feel pressured to spend more than you can or want to, just to please your coach. It’s hard to tell online of course - maybe she’s just advising you that what you want is going to cost you more than you’ve budgeted. But you absolutely do NOT need to spend 6 figures to do well here in Ontario at the lower levels.
