As a dedicated tank, I’m facing quite the head-scratcher: my DPS just isn’t cutting it, barely reaching 20k-25k at its peak. I’ve been diving deep into countless tutorials and guides, trying to figure out what’s holding me back, but it’s like hitting a brick wall. I’m feeling a mix of confusion and frustration, unable to pinpoint the exact cause of this problem. I find myself at a critical juncture, desperately seeking some much-needed guidance and advice to break through this slump and take my performance to the next level. Any help would be a game-changer for me
you not popping vampiric blood and dancing rune weapon enough?
Yes I use them as much as I can.
Blood DK is at the bottom of Tank DPS so that probably isn’t helping you much like best advice that can be offered is get DPS trinkets and embelishments 
Looking at your armory profile, I’m gonna guess that you’re issue is simply raw ilvl. At 397 you can do more thank 25k with smart pulling, but not a lot more.
I think you’ll find that as your ilvl goes up you can pull more, and as you pull more your dps goes up considerably. DRW is a pretty solid scaling that way.
I comfortably do around 40 to 50k overall in an m+. It’s not great, but it’s what a 427 ilvl let’s me do without too much hassle.
Link your any of your logs . BDK damage is absolutely fine now, solo target could have been 10-15% higher but that’s bearable considering you are a tank.
My damage breakdown at the end of dungeons is usually:
- Blood Boil
- Shattering Bones (I don’t usually play with Bloodshot)
- Landslide - trinket from Neltharion’s Lair
- Melee - Sad that our auto attack ends up so high on the list. Testament to our abilities not doing enough damage.
What helps my damage a lot is items that have a locked in damage amount. NOT items that give you strength boosts. So, trinkets like Mark of Dargul or Windscar Whetstone. Onyx Annulet. Phial of Glacial Fury.
They’re expensive if you use them a ton, but for higher keys I use Bottled Putrescence. It does a lot of damage on big pulls.
I am not sure how you could be deep diving into countless guides when you’re not following them.
-
Get rid of Rune of Apocalypse and use Rune of the Fallen Crusader - ALWAYS.
-
A lot of Blood DK damage comes from external sources. Get the proper trinkets and that will increase damage quite a bit. I can’t see what primordial gems you’re using - but fix them if they’re not the meta 3.
-
Playing blood shot is free damage.
-
Always be pressing buttons, don’t have free globals.
-
Without logs nobody can tell you what you’re doing wrong. Only tombstone after DRW, while standing in DnD, and having several stacks of Boneshield.
-
Sim yourself on raidbots. Use droptimizer to find gear upgrades. Look what gear top DKs are using.
Edit: 7. You don’t have any embellishments. Get the Frostire Belt and Shadowflame boots or double shadowflame. Again, a lot of our damage is external.
Gear issue mostly.
You’re 397. You have an Onyx Anulet on with no filled sockets, which is EXTREMELY hurting you since the Onyx Anulet offers no stats besides stamina.
You have no tier set bonus of any kind from last tier or this tier.
- Go get your sockets filled for the Onyx Annulet
- Get yourself some tier gear, the set bonuses literally benefit you in every way.
Literally just Simmed your Blood dk. Your simmed damage is 21996. Get your sockets filled and get some actual gear and that number will skyrocket.
