DRK Defensive CD's. Am I missing something?

You have to use your TBN all the time in order to make it working during big pulls.

DRK is defficient in deffensive department, he no longer could heal himself for large amount of HP, has to rely on TBN and rotate it between cooldowns.
Also dont forget to use Arms lenght from role actions, it reduces the attack speed of mobs if they hit you, pretty useful.
