I just recently switched to Holy and am really used to using rawr with my ret set to find upgrades and determine which gear to go for, but when looking at holy gear on rawr I noticed some strange things. For one, rawr recommended gemming for socket bonuses, using 10 Int 5 Mp5 or 10 Int 12 Spellpower. And for meta it recommends the http://www.wowhead.com/item=41376 (Mp5 and 3% Increased Crit Healing Effect) for meta. I was under the impression to use Brilliant gems in all sockets with one Nightmare tear and http://www.wowhead.com/item=41401 (21 int and chance to restore mana) for meta.
Seeing these differences I was wondering how accurate rawr is for holy? Or are there some settings in rawr I need to tweak?
