DPS for DK Tank: Blood vs. Frost
My small guild is currently progressing through Icecrown Citadel. We are doing ICC-10 with two tanks; both of us are Death Knights -- I'm Frost and the other guy is Blood. I have no complaints with my threat, and I know that our job as tanks is not to be the #1 DPS, but I confess I have DPS envy. (I should add that nobody complains about my DPS, except for me.) My problem is the Blood tank. We have nearly identical gear (I have Breastplate of the White Knight and he has Ghoul Commander's Cuirass; everything else is the same). I'm lucky to break 2k DPS and he consistently does at least 2.5k. He has gemmed exclusively for stamina where I have a few +agi, +str, +crit gems, in an attempt to increase my DPS. Finally, last night, I took a look at his character in the Armory, and I was amazed. With identical gear, he has 300 greater strength, 150 greater agility, 4% greater crit chance and 1,000 greater attack power. No wonder his DPS is so much higher than mine!
Is Blood really that different from Frost in terms of DPS, or am I missing something? It's hard for me to believe that Blizzard intended for a Blood tank to do that much more damage than a Frost tank. I have no problem with threat, but the other tank doesn't either. I'm wondering what unique things I bring to the table. Our primary role is not damage, but the more damage we do, the faster the boss goes down, so it's not like our DPS is totally immaterial, seems to me. Should I stick with Frost or switch to Blood? How does Unholy compare?
