Holy Pally dungeon farming?

right now i have a lvl 70 holy pally (http://www.wowarmory.com/character-s...kar&n=Vangarde)
i can 3 pull SM Cath but my rep bill is through the roof! over 100g if i let everything break... (sometimes i dont notice)

I started to run gruuls with my guild before i got fed up of raiding...
is there a trick to using a holy pally that i dont know?

just need some advice as to what i should to make it easier to farm instances

currently have a 40 mage that i am PLing (http://www.wowarmory.com/character-s...Char%C3%ADzard)

I have a 70 holy pally that I grind undead strat with.

Check my spec, I think it works great for both PvP, PvE, and soloing instances. http://www.wowarmory.com/character-s...ndare&n=Athala

I use this shield Petrified Lichen Guard from Sporeggar rep with a shield spike along with blessing of Sanctuary and Retribution aura. I pull 3-5 groups, consecrate, holy wrath, and then let them beat on me while I heal myself. I've found using the S1 PvP holy gear works well.

The biggest problem is that while you are epic'd out your gear isn't really grinding material. As mentioned above grinding UD would be best for you. Now if you spec Prot and put on even decent greens and get a shield spike you could own SM.

Just looked at your spec and none of the retribution talents are going to help you much in aoe farming instances. Redoubt alone will save you a ton of money as you block lots of hits when you fight mobs 10+ levels below you. And if you use Sanctuary/Sporeggar shield/shield spike, those blocks equate to damage back to the mob. Its so much fun to have 30 mobs in a half circle in front of you and watching the scrolling combat text spit tons of numbers on your screen as they hit you.
