Many ppl know that quest : King of the mountain, but most of those (at least on my realm) do it wrong way : you don't need to stand on a surface to make another jump, just spam jump button and point anywhere on the rock makin closest path you can do. Sometimes it cause camera to come very close to jumpbot, but still it's fastest gold in game.
Actually on this video I haven't done optimal path, it just show the idea of that trick. You can master your jumping skills and make it in about 20 seconds. GL and easy farming.
