This is purely theoretical, as I don't have the items yet, but I'm okay with them. 5% off Rejuv isn't great, but considering how much more of a role Rejuv plays in my healing than it used to, it's not bad, and will actually have an effect in almost every fight. The bonus healing to Nourish is very situational, and once I have 4T7, I'll most likely at least carry around the pieces to toss on during an extreme tank damage fight like Patchwerk, where rolling Lifebloom and Rejuv will add another 10% to Nourish for getting them topped off. I certainly don't plan to make it a point to keep either bonus to the exclusion of higher general throughput gear, though 2T7 is worth some regen in itself. Specifically:
Rejuv is 18% of base mana, or 3796 * 0.18 = 683 before talents/gear.
Normal: 683.28 * 0.91 (Moonglow) * 0.80 (ToL) = 497 mana
With 2T7: 683.28 * 0.91 (Moonglow) * 0.80 (ToL) * 0.95 (2T7) = 473 mana
Difference: 24 mana
(These numbers seem wrong to me, but I'm at work and can't double check my actual mana cost. Am I missing a talent?)
Equivalent mp5 with rejuv rolled on 1 and 5 targets:
One person: 24 / 3 = 8 mp5
Five people: 24 * 5 / 3 = 40 mp5
In reality, it's worth somewhere between those values depending on the fight, but at least it's a general idea of how much it's worth compared to intellect and spirit, if you're looking at replacing a piece with a similar ilvl but different stat allocation.
[edit] Apparently I can't divide simple numbers in my head. 24 / 3 is not, in fact, 6.
