I’ll add my 2 cents worth as a disc healer. I haven’t run any raids, but have about a 4.5k GS and ran H HoR the first (and so far only) chance I had without a problem. So anyway, keep in mind this is all in relation to 5 man heroics.
First, if you are bad about putting PI on a DPS, then go ahead and add it to a macro to cast on yourself. Better to be selfish with it than never use it at all
(Also, since I just do heroics, fuck em.) I currently have it set on my Flash Heal. But make sure you add a target=player, otherwise it won’t cast on you and may end up on some undeserving DPS! Oh, and it has no global cooldown, so you don’t even have to think about it. If anyone is interested I can post my exact macro when I get home. It has all the tricks in it to hide the error text and sound for when PI is on CD.
If you don’t have one already, get a timer to show your Weakened Soul debuff. I use DotTimer. As often as you’ll be bubbling (PW:Shield, obviously) people it is very helpful to know when you can bubble em again. Also helpful is an addon to show who is currently shielded. I use a built in feature in Xperl. This isn’t as necessary though, as at decent gear levels and properly specced, your bubble costs next to nothing to cast. So I don’t worry about bubbling over an existing bubble.
My rotation:
PoM and bubble the tank
Bubble the guy below him
Bubble the guy below him
Bubble the last guy
Bubble yourself
If you see or hear PoM go off that means the tank’s bubble is broken
Go ahead and pop a renew on him
If his Weakened Soul debuff is gone, bubble him again
If his weakened soul is expired, start rebubbling everyone in the same order as before
???
Profit!
So there you have it, in a good group that’s just about all you need to do. In a bad group, stick with that general idea, but add Flash Heals, Binding Heals, Penance, Greater Heals and Prayer of Healings as needed. Oh, and if it’s a situation where the tank holds aggro well and there is no AoE damage do this: PoM and Bubble tank. Go grab yourself a beer. Make a sandwich if you are hungry. Return to the fight to watch it end and get credit for “nice heals!”
As for stats, from what I’ve read it’s:
Int
SP
MP5
Haste
Spirit isn’t as important to us as it is to Holy Rollers. We use MP5 instead. I’m not gonna go anymore into stats though, as I’d just be regurgitating what I’ve read online.
Oh, one last thing, and this is only for total newb healers (read: me a month ago) +hit is useless to a healer, as all heals will hit every time.
