Comparing Unholy and Blood using Deathcoil. For easy math let's say the DK has 10k AP and 50k Health.
Deathcoil does around .3AP damage, so the unholy DK will crit for about 6k.
The blood dk will get an extra 5k attack power with max vengeance, putting him at 15000 ap, and his death coil will crit for 9k..
Even with unholy talents buffing the damage of Deathcoil, it won't deal 50% more damage, and that's just for 1 attack.
Am I missing something? Because that just makes a tank seem undauntingly powerful. And higher health pools in Cata only increase vengeance ap gained.
