Hey john, wasn't sure if I found any useful replys after the 3rd or 4th page of this topic, just wanted to give you my 3 cents on your healing gear.
I think you got a pretty good idea on what to gear for, however the thing that makes holy paladins better than other healers is they have an armor advantage vs melee classes, and since the most current patch, we now gain SP from Int gear which is a huge bonus for us. Since armor is our advantage, it's good to abuse it and not ignore it. Now it's true, in most cases, stats > armor for leather/cloth users and in
some cases even paladin casters. Now I've twinked in plenty brackets from 19s to 60s and hopefully 69s too someday with my Holy Paladin, and not once have I never found this useful tip to be NOT helpful. Your armor rating wants to be no lower than
44% reduced melee damage. Having higher armor than that isn't a bad thing but you
might be hurting your stats. In the 19 bracket, you usually will hit around 44-46% reduced melee damage if you have BiS healing gear.
Another thing I want to add, you should always have some hit rating which I didn't see that you had. In most cases, you will probably cast Hammer of Justice, Judgement, even holy shock(on the enemy) from time to time, and melee hits in a WSG. So it never hurts to put on some hit rating gear.
I went ahead and made you this gear guide and I hope this will be helpful to you. Use it if you will, but imo(others might disagree) this is the BiS gear for a holy paladin.
