While we are on this topic. I would actually like it if they would be fair about mounts. Yes, WHM gets a Unicorn, tanks get their beloved achievement mounts. But what about us DPS, SCHs, ASTs? We all deserve to gain achievement mounts just like tanks (heck, even WHMs could use achievement mount too!). Healers has it incredibly rough just like tanks, even DPS. I find just giving tanks achievement mounts is unfair and very well unbalanced in this game.

Also, on topic: I was also disappointed by how Kirin's music was generic. The same as others. I was thrilled that Primal Mounts had their own representative music from the fight itself. Every mount should have a unique piece of music. I agree with the OP.
