I searched but didn't find quite what I was looking for so..
I am currently running with Trauma (http://www.wowhead.com/item=50028) + Shriveled Heart (http://www.wowhead.com/item=50309) as DISC. I was using the +113 hit staff from Heroic PoS and the only other person who rolled was another disc priest, otherwise I would have passed on it.
In ICC 10 tonight, Mag'hari Chieftain's Staff (http://www.wowhead.com/item=50805) dropped and no one else needed it, so I rolled OS for it and was the only one. I am really at a loss about which one is better for disc.
The proc from Trauma isn't very good for disc, in my opinion. We did 6/12 in ICC 10 today (inb4 lolurbad, this is a regular group who progresses through icc 10 2-3 days a week and are 10/12 atm) and it totaled out at 0.7% of my healing which is lackluster. IMO, it'd be much better in the hands of a resto druid/resto sham/holy priest (no, I do not want to go holy).. hell, even an H Pal.
With Trauma + Shriveled Heart, I get 87 int, 50 haste, 882 sp (counting the +63 enchant), 51 crit.
With the staff I get 101 int, 136 spirit, 784 spell power (counting the +81 enchant and 2 runed rubies in the staff) and 136 haste.
The raw SP on the mace is nice, but I have a very decent bit of sp but pretty crappy regen.
I am currently sitting at 3107 SP, 499 regen, 591 haste, 27.52% crit (32% holy crit) unbuffed. Which should I use?
Thanks in advance!
