To be honest, that 25% more damage taken isn't really a problem, as its taken more smoothly, allowing healers to heal using their efficient heals (In my case, Rejuve, Lifebloom, with some polish from HT) to heal the BrM, saving them mana in the longer run. A DK requires a much more judicial use of Regrowth to "safely" keep up (Curse blizz for nerfing the shit out of DKs, used to, good DKs were also a pleasure to heal due to the powerful nature of their AM. Now? Not so much - At max, a DK can heal themselves for 60% of damage from a spike, which requires significant pooling of resources to do so. Pitiful.
