When the Golden Lotus Daily Quest Sprite Plight is up, a number of mobs named Slateskin Troublemaker Spawn in Mistfall Village. These mobs have low HP and drop loot.
This can be used to farm Skyshards, Motes of Harmony and lots of greens.
A guildmember of mine got 7 of his skyshards in about 5 hours of farming last weekend using this method.
Ranged With pets are best for this as the Slateskin Troublemakers have a stun, and having a pet eat the stuns helps speed.
Put Free for all loot on, have one guy loot the motes and the other loot skyshards greens and such.
The location waypoint is 38.95, 79.42 (Screenshot of Location) (Screenshot of Map)
Tag a bunch of Troublemakers, AOE down when pet has threat (hunters can MD), Potential profit.
