I’m unholy and I’m torn between venthyr and necrolords so I was curious what you other dks are picking and why?
Necrolords is solid all round for DK, plus the armor looks 
I really dig the Venthyr theme and rewards so I went for that. While leveling, I also found that the Venthyr ability was much more useful than the Necrolord one. Less damage but lower CD and the RP makes it versatile for spamming Death Coil/Epidemic or Death Strike. It’s also loads better for Blood. Abomination Limb looks way cooler though.
I really liked using Shackle the Unworthy but I found it just wasn’t as useful as Swarming Mist.
Necrolords is better if you plan to one trick Unholy, but if you’re looking to play DK as a class, I think Venthyr is by far the best option.
I’m on Necrolords, and I like it, but when I play Blood, I can’t help but wish I had Swarming Mist instead of Abomination Limb, Mist is just so much better at getting immediate Bonestorms off. Abomb Limb is also awkward for 2h frost, which is the only mode of Frost I’ll reasonably play, cause I’m not fishing for 1h drops. It lines into Obliteration very poorly. The HB procs are redundant during Obliteration, but Abomb Limb does so much damage that you don’t really want to cast it clean without Pillar up.
I ended up going Night Fae because the active ability seems decent for all specs and the signature ability helps us who are super slow.
I went Venthyr because door of shadows just felt too good to pass up for skipping things and getting to places that you couldn’t normally get to as a Dk. The swarming most ability definitely has helped a lot with the RP generation too.
Honestly, what are your priorities? Do you make any decisions based on pvp viability? Do you want to minmax real hard on pve? Is roleplaying important to you?
With that in mind, in my experience and studying the topic for days:
If you want to have pvp viability:
Necrolords - huge tools against and for cc, aoe pressure, but you need to be smart to use it. Very rewarding and fun.
Kyrian - nice burst, nice defensive value on flat damage reduction and steward. Simple and effective.
If you want to minmax hard:
Necrolords - really good st and aoe, can help with fleeing mobs
Venthyr - amazing aoe burst, pretty mediocre in st. Good option for m+ players I guess.
If you don’t enjoy any of this or fantasy/roleplay is your priority… honestly, pick whatever you want. They are all viable in that case. Just learn how to take advantage of it. There’s not a huge difference in perfomance between them pvewise.
Yeah I went necro I really wanted to go venthyr i just like the zone alot better but considering pvp and pve necro did appear to be stronger for my playstyle
Necro was the correct choice (at least until the next tuning pass) by all observable metrics that I am aware of. Both of its abilities are extremely powerful in all forms of content. As much as I and many others wanted to choose Venthyr for the much needed boost to mobility, it was simply overshadowed by all the nastiness you get from going Necro.
Agreed both are strong picks just one is alittle more shiny lol
The covenants are close enough i think where you can pick the theme you like best tbh and you wont be gimped whatsoever. Blizz is extremely focused on tuning passes for covenants. I took necro because it fit the dk theme and i love the abomination limb ability, but the ventyr armor amd abilities are sweet too so if you prefer that just roll with it.
3-4% difference between Necro and Venthyr overall, I think it was. Not a big difference, but it’s enough of one to dissuade a portion of the player base from wanting to use the latter.
I went Venthyr after a tough struggle between them and Necro. It was a tough call because they both thematically fit my dk. Ultimately what sold me was story, zone, and ability use. Mists being a big consideration.
On paper Mists is less dps than Limb, but the pull on Limb was causing me to hesitate on when to use it and thus not utilize it in certain situations. Mists is almost always usable so it contribution to my dps is much higher, plus the extra runepower is nice.
Also I love the visual animation. 
So far I am not regretting a thing! 
The overall best answer is Venthyr. It will allow you to be flexible with DPS/tank, mythic plus vs raid vs pvp. Also gives you the neat Door of Shadows.
