These are not exact quotes but generalisations.
Blizzard in legion beta "Each spec should feel different and have its own identity. Specs should be tied to class fantasy."
Blizzard now " All hunters are the same so we are only making one mount"

There are a lot of ideas but one perfect example of spec uniqueness is BM could tame a "spirit beast mount"
EDIT: If it is only color variation then i retract this.
