This question of mine has not yet been answered in the Restoration Shammy Think Tank, so I'm asking it here: though I believe the answer may be ambiguous.
I am raiding 25 man Naxx and am currently specced 0/17/54. I was wondering if it should be considered taking points out of Improved Water Shield, or Healing Focus, and putting them into Ancestral Awakening (AA). I do understand that AA is only effected by beneficial healign amounts, however I am finding that most of my casts are Riptide and Chain Heal, with the exceptions of Patchwerk where I spam LHW (glyphed).
In addition, I am also currently stacking +16 intellect gems (to gain full use from Replenishment, Mana Tide) and am currently on 20,000 mana unbuffed, what should I am for? (I myself think 25,000 unbuffed).
On fights like KT or 10 man saph(CH not always reliable) LHW spam usually runs my AA healing anywhere from 5-10% of healing done on WWS....definitely not something to overlook.
As far as gearing, by the time you reach 25k unbuffed you will certainly have a good amount of crit from that int, and your spell power may or may not be to the point where much of it is overheal already. Obviously the "more SP is still efficiency because the more you heal the less you need to" argument still applies despite no more downranking but realistically.....whenever I think about gemming something other than int, I just feel like there really isn't a point at the moment.
Also, not sure if people are factoring this in, but as soon as you drop 2piece t6 you're going to lose over 200 mp5 while chain casting CH. So if you think your mana is infinite now that may change a little when you upgrade to all 80 gear.
[e] Tip for you since you're a JCer. You can use 2 27 int dragonseyes in those trinket sockets and you'll keep the bonus. You may be in the same boat as me and your guild has only been buying patterns atm, but thought it was worth mentioning since blue sockets are still less than ideal.
