DRK Defensive CD's. Am I missing something?

Yea I was wondering about this as well. Glad people explained it.

BTW how exactly does TBN work?

It gives you (or someone else you use it on) an absorb shield for 25% of your/their maximum health at the cost of 3,000 MP. Other forms of mitigation are taken into consideration before TBN's shield; rampart, shadow wall, or what have you will all reduce the amount of damage the shield itself takes.

Most tanks have 120k+ hp now meaning TBN will give you a shield that prevents 30k+ damage every time its used. This is in addition to any mitigation from other cooldowns being used. On large pack pulls it may only last a few seconds. But that's a few seconds of zero damage giving your healer time to heal. Then use Abyssal Drain to restore hp as it falls off and use again every 15s in large pack pulls.
