Blizzard has posted a Dragonriding blog, going over the basic and progression of Dragonriding in Dragonflight!
A skilled Dragonrider is a force to be reckoned with, capable of catching up to any foe, ambushing enemies from above, and soaring above the Dragon Isles with impressive speed. Becoming a Dragonrider and learning the basics will be simple, but mastering this new skill takes practice. Once you figure out its intricacies, you’ll never see the Dragon Isles the same way again.
