I see your point, but a lot of the things in game are about making the game even for both sides. Before cata the alliance had more ally-only questing zones than the horde and in cata they made it more even. When the goblins got the trikes and the worgen got the cool running(pun intended) they added generic horses for worgen to even out the mount count. Or the wintersaber and the ravasaur mounts. The ravasaur was just a quest a day for however many days, and the wintersaber was endless rep farming. then in cata they made the wintersaber mount quest like the ravasaur, help your cat grow once a day for however many days.
