The Jewelcrafter-only secondary stat gems are well under budget compared to some other professions.
Just to be clear I am not talking about Strength Intellect Agility Stamina.
Jewelcrafter only gems secondary stats are giving +160 additional, which is half the bonus that they should be.
Example: Sparkling River's Heart gives +320 Spirit. Sparkling Serpent's Eye gives +480.
If I was a Jewelcrafter, I would get a total of +320 Spirit for socketing two (480-320=160x2=320),
whereas a Blacksmith would be getting 640 (320x2=640).
If they are inflating secondary stats to make them a viable choice, they need to do the same for Jewelcrafter gems, or they are NOT viable options.
