When my Dad was showing all the time, he would very seldom train a horse for only 1 discipline. Most of the owners wanted as many points in any class they could get. He would rope, rein, WP, and halter the same horses. Everyone said that no horse could ever be a winning horse in any particular class unless that was all they did. BUT, Dad's horses almost always won. His halter horses were beefed up from roping and reining, his roping horses were relaxed and calm because he showed them in WP. His WP horses still had natural gaits because they were also shown in reining, and his reining horses never got pattern sour because he roped and did WP on them. I love an all around horse that I can take on the trail one day then go win a show in any discipline I am in the mood for on the next.
