Until my guild starts raiding, I've been running every heroic under the sun. I've been pretty successful so far, and a lot of that success has to do with my gear. Obviously I'm going for plate gear with intellect on it, but what do I look for once I've found the intelligent plate?
What to go for.
First of all I want gear that has spirit on it. If I have a peice that doesn't have any spirit I want to reforge either Crit or Mastery for spirit. Second, I want gear that has haste on it. Haste makes the global cooldown and my cast times slower, and with enough of it I get an extra tick from Holy Radiance. I try to reforge crit or mastery to haste. Crit is preferred over mastery, but I'm not going to reforge for it anytime soon.
What to gem for.
I like to match sockets, so for red gems I go with +40 int gems, yellow sockets get +20int +20 haste, and blue gems get +20int +20 spirit. This way I'm getting my main stat, intellect, and the spirit and hast I need as well.
What to enchant for.
I go for intellect enchants, spirit enchants, and haste enchants for my gear. Same reasoning as before, when enough haste I can increase my output, and with enough spirit I won't run out of mana.
So far that has been working pretty well for me. I haven't had any mana problems, and there are very few times where someone dies as a result of my healing. They might die because they stood in the fire for too long, but rarely is it because of my inability to save them.
I hope this helps you with your gearing choices. It has defintiely helped me.
