Design: Agile Primal Diamond

Where does this drop ? I've been trying for days now and wowhead aint really helping. Its the 216 agilty meta gem recipe. I see people see it on AH but ofc no1 ingame want to tell me how they got it. It's every man for himself and non wants to share. So I'm hoping anyone here would be willing to share? http://www.wowhead.com/item=83811/de...amond#comments tried everything what it says here but no luck what so ever. Guo-Lai Halls issn't working as it should be...

On lots of places, keep farming. Check the "dropped by" tab for more details.

I did see the dropped by tab but I'm having no luck in getting the recipe. That's why I made this topic. Who actually got the drop and from which mob? Can you confirm that it drops?

Anyone? There must be somone who knows...
