With all the AOE trash pulls DnD on top is no surprise. HS and RS were absolute staples. However, with all the AOE I need to get in the habit of using blood boil, especially when 3.1 hits.
Overall by DPS was 1655 which equates to 3,144+ TPS. The DnD and RS would bring that average higher. The threat is not as consistent as it is with Unholy. It is much more dependent on strikes than disease damage or DnD so it varied a lot. I spiked to 5k several times but barely had 1k at times as well.
Mitigation wise I feel the absence of Bone Shield with this spec. That lead me to using the rare health potion a couple times. I'm not about to say blood is squishy. I didn't stay on top of my cooldowns. I never used IBF and I think I remembered vampiric blood twice and rune tap 4 times the entire run.
They only concern I have prior to 3.1 is snap AOE aggro. As unholy I would have blight up the entire time you do the gauntlet after the third boss on the way to getting the mount if you beat the timer. Towards the end of the gauntlet the last pack of adds aggrod on us and my runes, DnD, and empower rune blade were all on cooldown. 4 mobs aggrod and ganked the healer.
When 3.1 hits that won't be an issue since you can hit blood boil to pick them up. Just something to watch out for in the mean time.
