In the newest Dragonflight Beta build, Blizzard added new summoning animations for the Dragonriding mounts! These animations now showcase the mount arriving from a distance and the player jumping to mount on them.
According to the first quest in the Dragonriding introduction quest, Dragonriding, some of the drakes of the Dragon Isles have expressed interest in wanting to explore every nook and cranny of the continent, and they’re eager to work with you on that objective!
