WoW - Best place to farm for green drops/Windwool clothes/Motes of Harmony for level 20s

This guild is for people who are trying to twink at level 20. The character in the video has elemental force enchant and the average item level is 26. It might have been faster to farm if it was a mage with a second alt toon to heal. The cord/location is shown at first second of the video. Good luck on farming.
