I don't think epic gems are worth it. 160-200g for an extra three stamina is ridiculous.

That said, I'm considering upgrading my [item]Solid Star of Elune[/item]s to [item]Solid Empyrean Sapphire[/item]s. Why? For no other reason than to pimp out my toon as much as possible. Having 12 non-meta gem slots to fill with SES's, that would gain me 37.8 stamina (I don't really know how that rounds). Which is approximately another 378 health. I could then upgrade my [item]Clefthide Leg Armor[/item]...
