The fact that you can say that you go back to farm content, heroic or not, and say that all 4 tanks are on the same page does not necessarily make me feel any better.
Then why are you trying to tank a DK if you feel they are so inferior. I'm going to guess you either have bad timing on your healer cast time vs incoming damage or you are not chaining CDs properly during the kill zones of incoming boss damage. With no tank tree, but only tanking talents and unique utility from DPS talents you have to approach damage reduction much differently.
DK tanking is basically bear tanking from plate. Avoid as much damage as you can. Warriors and Paladins want some damage since they need to take damage to regenerate resources.
