This topic is intended to point out some of the issues with Blood DK and consider ways to improve it.
Background - I’ve been playing DK since they launched in WotLK. Frost, Blood, Unholy. Many, many hours through a number of expansions. Spare me the L2Play thing, I know how to play it.
Blizzard recently buffed the armor bonus we get from Marrowrend, thank you and it does help, but they still feel squishy to me against tough mobs. I play a number of tank specs. Where is the passive damage reduction that other tanks get? Not in my spell book!
Another big issue is with Death and Decay. It lasts 10 seconds, but the cooldown is 15 seconds. That means 1/3 of the time, your heart strike is not cleaving and it’s not helping to hold aggro on a pack. It also means that Death’s Due (Night Fae ability) buffs/debuffs are pretty much guaranteed to roll off. People say “Crimson Scourge procs”. Those are unreliable. If you wait for those, those buffs are rolling off much of the time.
Protection paladins can keep up their consecration all the time. They get damage reduction for being in it. On my pally alt, Consecration lasts 12 seconds and the cooldown is 4 seconds (in lousy gear). Doesn’t it make sense to be able to keep Death and Decay up all the time?
My suggestion: make the cooldown shorter or the same length as the spell duration for Death and Decay. There are Torghast powers that play off Death and Decay. Not being able to keep it up 100% of the time hurts their value, too. Also, the Phearamones legendary plays off it.
You might suggest using the Death’s Certainty legendary to reduce the cooldown for D&D. Guess what the expert says in the biggest online guide? It’s not worth using, even for Night Fae. The legendary choices are weak.
Why does Crimson Scourge have to proc Death and Decay? Make it proc a free Death Strike if you want it to be powerful. Make it proc a use of Vampiric Blood that adds damage reduction.
Using a Blood DK is a pain most of the time. The “pros” who run it know exactly what kind of damage and when the damage is coming (i.e. raids) and they work around it. The average guy tanking watches his health bar drop way down, scaring the healer, and then tries to get it back up quick (like running in Mythic+).
What happened to plate armor being tough? Standing in Oribos in full plate and my damage reduction sucks. Sure, once you get a Marrowrend hit in then you start to see some alright reduction. Don’t ever let that Bone Shield fall off, or you’re in big trouble.
My suggestion: make Blood mechanically easier to use (fixing the Death & Decay duration or cooldown length), give it more baseline damage reduction so it’s a real tank again, and tone down the healing some.
If we are going toward a kiting meta, then you may even want to put a damage reduction on Vampiric Blood and add more mobility. Make it jump like Vengeance Demon Hunter and Protection Warrior; something.
I want to love Blood DK like I used to, but I can’t. Thank you for your time, this trainwreck can be fixed. That is all.
