Hey there, i'm new on the forums and i wanted to point out that you can get the going down achievement really easy at orgrimmar if you're horde, when you use the right lift up to the wind rider platform, just move left and face towards the orgrimmar gate, you see a large drop and if you jump you should get the achievement there. (i jumped on top of the mailbox at the bottom and it left me with ~1% hp and achievement
) i can provide the pictures if someone wants to achieve it that way
edit: fixed some grammar errors
