normally i'm playing disc in my raid. what i think about is speccing on holy for immerseus with dd trinkets. Here are the options:
1. I'm playing disc, do my ~50-60k dps through attonement and play the boss like a normal disc
2. i specc on holy, put on dd trinkets, do my 100-120k dps in phase 1 and switch to healing when phase 2 is beginning or later in the fight when in phase 2 are more blue ones to heal
While in nhc it doesn't really matter i think, maybe this could be a little help on heroic to support the dmg of the group and also heal when it is needed.
What do you think of this ?
