Me and a lot of other players haven't been able to learn the Cloud Serpent Riding because the questline is bugged. When you accept the quest Empty Nest from Instructor Tong you are unable to complete it because the Windward Hatchlings aren't affected by the provided item Silken Rope. I think this is a mayor problem because if most of the players can't learn this skill (Cloud Serpent Riding) there will be a lot of in-game experience we are going to miss, and a lot of mounts we are never going to ride :sad:. I hope this problem will be solved as soon as posible. THANKS.
