Ok.. I went through azjol-nerub and the tank, who must of been on his period, was having a cry about the dps sucking.. as it usually does when you use the random dungeon finder.. anyway at the end of the run he turns his attention on my (the healer!) and says that I'm a fail 'Holydin' cause im using the new frost badge libram (Libram of Blinding Light).
I asked him what was wrong and he said that i need to study up on my theorycraft and to become a better holy pally i need to use the ilvl200 libram (Libram of Renewal).
so can anyone tell me HOW does saving a crappy 113 mana on a holy light is better than using a libram that is in our Teir 10 4 peice set bonus..
