Are there any good or known farming spots for Skyshard to drop? I have spent several hours farming the Mogu in the Vale of Eternal Blossoms in an attempt to get the ten Skyshards needed to craft the Sky Crystal. I currently only have one of them and came from the mogu during my farming. I do now for a fact that some mobs change/disappear depending on the dailies that are available that day. So my question is: Where is a good farming spot in Vale of Eternal Blossoms with minimal downtime between mobs.
As the other answers said - no real 'good' spot. Where and what you are doing is probably the best you can hope for. I did the GL dailies everyday until I reached exalted and never got a single drop, and as far as I know only a couple other members of my guild have even gotten a single drop.
The mogu in the daily area are probably the your best bet.
I have a feeling that with the next chapters of the expansion they will drop more or be a drop from a dungeon/raid boss. Which may also be a possibility, but again have never seen one drop in a heroic or LFR.
The Shao-tien Marauders, Soul-Renders, and Stonebark Tricksters have the best chance of dropping it - about 1 in 300 chance (0.3%). There is a large cluster of these in the north of the Vale around 36, 24. If you can AoE them down... that might be your best shot.
Good luck, it'll be a hell of a grind. I'm exalted with Golden Lotus on two toons and only get one drop!
