(I posted this over on H2P, but patience most definitely isn't a strong point for me).
So the other night I received a normal mode Dysmorphic Samophlange of Discontinuity and found it provided me much more mana on average than I was expecting (using a heroic HLG for my second trinket)... Because of this I decided to drop down from 17k Spirit (Holy) to 15k and started gemming Intellect to replace the Spirit.
Here's where I am a bit confused... When I go to Adinne's page and import my toon from the armory and check the HPS of each spell in the Delta Viewer, it shows mastery as being weighted significantly higher than Intellect (after doubling the secondary stat). Intellect being ~1.3 and Mastery being ~1.6. I've always followed the guideline that 1 Intellect > 2 Mastery... So what's going on here? I would understand going Intellect over Mastery if they were close to each other (since Mastery doesn't affect Lightspring, Sanctuary, or Renew) but a .3 weighting difference seems pretty large to me. Especially considering that I won't be getting four part tier until after the dps (and I'm not using Sanctuary too often until then) and Renew is a minimal portion of my healing done.
The main negatives I see with Mastery is that it has a greater chance to overheal and I lose a small increase to Lightspring (and Lightspring has been wonderful in progression, don't get me wrong)... But to be honest... While working on heroic progression Echo of Light is often in the top three spells (if not the top) for healing done by me (while Lightspring floats around #7 - #10 in most fights). I'm kind of tempted to drop a little Intellect (I have ~31k Int in a raid and ~52k Spell Power) and bringing my Mastery up from around 28% unbuffed (dropped a little cause I'm experimenting with the 4721 Haste breakpoint) to 33% or so.
Any thoughts?
P.S.
25 man btw.
