yep! i don't know for sure but since i hear western pleasure sometimes called the western version of dressage i assumed it was intentional lol. the nice thing is that western pleasure and dressage horses can freely switch between their discipline or even do both at the same time! though i can see that it could feel odd as the IRL disciplines are quite different.

I can understand this logic I suppose but I am not really sure if it provides that much benefit to the user other then opening them up to another show group with the same advantages. 
I also feel like it throws off the balance of the discipline table as it removes a possible acceptable arrangement of stats. 
Im not sure though but this is the current distribution of the number of times each stat appears in each column
Speed 4 2 2 → used  8 times total

Endurance 3 3 1 → used 7 times total

Flexibility 3 1 3 → used 7 times total

Intelligence 4 4 2 → used 10 times total

Agility 2 5 4 → used 11 times total

Power 2 2 6 → used 10 times total

 

HUS and Hunter have the same stats as well. With limited stats in game, its bound to happen with similar disciplines

that's fair! i think it'll even out more eventually as new disciplines get added, though it may take a long time as that's not being focused on right now.

@Maki the 3 stats are the same but the primary stat is different between Hunter and HUS. Cross Country and Flat Racing also share stats in a different order too.

I think the hunter and HUS makes a lot of sense having the same stats in a different order. I think it actually is super beneficial to the user. For example, I have some horses I am going to run in hunter but train some in HUS to bring up the Agility stat in my horses. I think if Western and Dressage complemented each other like hunter and HUS do it would benefit the users more.
