The last horse I have ridden that was anticipatory? She's a beautiful, amazing animal. She's incredibly smart and one of the most incredible liberty horses I have ever seen. But anticipatory? She'll do three things before you get finished asking something of her, and none of it may have been what you asked.
See, you're getting caught up in the showy aspect of dressage. Like dressage horses are prissy, clean, stalled animals that can't be out in the rain and mud, working with sheep, cattle, and dogs on a range. That is the pristine English image you are getting caught up with, which is also reflected in Western disciplines by the way. They are still working animals though that are just as capable of ranch work as Quarter Horses. You may not know, or just not remember, that the many of the favored dressage breeds, PARTICULARLY the high school/haute ecole breeds, are bull fighting horses. The skills they learn to perform in a dressage arena are used in arenas against bulls. Not a working cow horse, huh?
Dressage is not a submissive, listen to the command of your rider, type sport. It is all about the abilities of the animal and the rider as a team, what the animal is capable of, what the rider is capable of. That the sport of Western Dressage is not meshing to your liking is not the fault of Dressage as a discipline, but the fault of those parading and performing it. They create the fashions and the fads, and there fore the sport as they see fit.
It shouldn't stop you from learning it. My dream horse is capable of pirouettes and flat spins. Of tempi changes and roll backs. Of extended and collected movement. Of sliding stops and levades. I want my horse to capriole and ballotade in the arena and pasture of his own will because he is capable of it and knows it, enjoys it, and performs it with out my guidance. He can work a cow, run a barrel, and piaffe his content down a trail.
My instructor had an Andalusian stud, just 5 years old, a little bit more than green broke, never taught anything of the aires above ground. We'd take him out in the round pen, and the first thing he'd do is roll in the sand. As soon as he was done, he'd get to his feet and jump straight in the air and perform a capriole. He was never taught to capriole, it is an advanced maneuver where they leap into the air, kick out their heels, and land squarely on all four feet. It wasn't perfect by any standard, but that he was capable of it without training... He had such strength and joy in him. He'd run freely, leaping into caprioles and such. I have never seen a Quarter Horse as fleet of foot as this stud is. He'd stop and turn so hard, I swear he could out turn any working ranch Quarter Horse that came through the barn. He was so much fun to just play with. To chase and try to out maneuver him. He was a joy to be around, and I hope the horse I one day buy for my own is just as capable and joyful of an animal.
To me, dressage brings out the best in the animals capability. I hope to bring out the best in my horses capability, to work with me. Not for me, but with me, in what ever we choose to do.
