Consider its common across breeds at their class A shows to drain the blood of horses before western pleasure, it's not surprising. Most people don't train their own horses they just hop on for the class, that's why EP and WP are usually fat fucks, they don't ride the thing on the regular. Unlike with dressage/eventing/SJ whatever, you have to train with the horse, you can't just pass it off to trainer, hop on and go for 3 minutes in the arena riding in little circles.
