It's not just an achievement, I don't give a damn about achievements, I want that mount.
Didn't they add new Night Elf and Forsaken 60%speed mounts in like 3.2 to give every race the same amount of mounts or something? Sure, this is slightly different, but whatever. It shows that clearly making things even matters, why else would they do that?
I mean, the people who go "Get over it" are people who clearly dont care much about mounts/achievements, so it doesn't affect them. If you were into PvP, and they decided "The Horde gets more PvP rewards than the Alliance" or whatever, the Alliance PvPers would complain.
It could be mounts, armor, pets, whatever, the point is we're getting nothing here, while the Horde gets two brand new mounts. I mean, we don't even get a reskin of an old mount. We get nothing. What the hell?
