Yeah, m8. You just gotta accept that favoritism exists in this world.
And maybe if you get the rep and get the Thundering August Cloud Serpent (dailies only); it might be bugged and does not require the cloud serpent riding skill.
Otherwise, yeah they are giving it out to a select few people. Nothing you can do about it, just don't let it bother you...
...Besides, cloud serpents (though I love my Thundering August for my monk on retail), are the lamest versions of dragons i've ever seen (really hate that type of dragon; Deathwing is definitely the best looking dragon in WoW, and his body style is that of a true dragon, imo.)
