Hi,
I was trying to discover all the pandaria recipes by crafting River's Heart.
The tooltip says:
Attempts to discover a blue Pandaria gem recipe of superior quality. If you have learned all blue gem recipes, you may discover a recipe for another color gem.
This porcess worked for one week or so. After discovering all the rare recipes for blue gems, i discovered also recipes for other colors.
Now it's more than one month that I don't get new recipes.
Is this normal?
