Insane amounts of +Healing at a LOW level

Ok, I've been working on leveling another priest lately.  This time, I'm going holy.

I guess you can say I've been conducting an experiment with this guy, in that I've been hoarding all the +healing gear I can get to the exclusion of all other stats including intellect and stamina.  I have also been leveling exclusively in PUGs in instances. 

I'm level 29, and I have +165 healing.  Getting this hasn't been easy... basically, I check the AH between every run and buy any greens 'of healing' that are upgrades in +heal.  I'm on a small server now, so they don't show up often.  It's not something you can do if you just walk up to the AH once - you have to keep going back and checking for upgrades as often as possible.

The result, so far, has been interesting.  I keep my groups healed primarily with Renew.  Primarily as in I never have to cast anything else.  I think on average in my runs of BFD and RFK, I've had to cast real heals (Lesser Heal or just Heal) about 5 times.  Healing has been so easy, I often throw out SW:P and whip out my wand and come in second or third on the DPS meter when there are two or more mobs to fight.

In one SM graveyard group at 28, my group chastised me for having only 700 hp.  I died a few times - partly because I was being sloppy - but mostly because we were doing it wrong.  Specifically, we had 3 priests, a warlock, and a shaman who couldn't tank.  Casting renew on anyone usually meant I was going to pull aggro because NOONE was bothering to control adds at all.  It was craziness.  Once they complained about my HP, and since I felt I was being watched, I adjusted my tactics, eliminated my sloppy, and didn't die again.  I basically let the level 33 priest do the healing and I just /assist'd the shaman.  I did pretty well on the DPS meter, considering I was using SW:P, Mind Blast, and Smite (holy spec), but the important part is that I didn't pull aggro any more.

What does this have to do with macros...

Well, I have this priest setup like my other healers.  I'm using Clique to control which spells I cast, so basically my usual method of healing is just right-clicking on my party's health bars to cast renew.  Alt-Left-Click is lesser heal, and Alt-Right-Click is Heal.

In PvP, I feel that sRaidFrames is essential, because it can fade out the healbars of anyone who is not in range of my heals.  This gives me an instant and continuous feel for who I can heal.  If they are in range of me, I heal them.

I'll update about this priest again later :)
