Something simple I came across. If you're looking for an easy way to get the Going Down? Achievement, check this out.
* In in the center of Dragonblight there is a tower called Wyrmrest Temple. Everyone will most likely go there while leveling since it has several quests.
* When you fly to the 2nd flower, you are fairly high. High enough to jump without dying.
