Well I'm back to the dilemma of wanting to heal instances in Northrend while I'm leveling, but not wanting to have a spec that does poor damage when I'm questing. Being Protection specked is awesome for grinding speed and completing quests where you just go to kill a bunch of mobs. But my heart still wants to heal :(. I tried a hybrid holy/retro build and did not like it at the end.

So the other night I downloaded the PTR and copied my paladin there. I then proceeded to respect into holy. I then went around killing mobs of my level to see my damage output. I tried it without using the exorcism since you can use it on all mobs now, not just the undead. Well after experimenting with different gear, that is trying the spell damage/intellect gear that I would use for healing, then trying my protection gear with the mace and shield. I finally found the best combination - I've put my prot/dps gear with a two handed weapon, and left a few pices to increase my intellect ( mostly rings and neck). And boom, there is a build you can level with.

Unlike all the other people who recommend for the holy build to rely on spell damage for the DPS, I say not so! It may be true for some great holly pally who is coming geared up epics from BC. I unfortunately only have the questing gear and stuff I can make with my Blacksmithing. So what i found is I don't need to buff my spell damage, it's going to be there automatically. If I add 600 spell damage the spell damaging spells will increase very slightly, but if I put my DPS gear with lots of strength and put my big two hand ax on, I got nice spell damage and a nice white damage from the ax. So it worked well on the PTR. I think today I'll try it on the life and see how well I can still quest with it. Here is the build I'll take, note that I'm putting 5 points into the strength talent so I can do more white damage.
