Если вкратце есть два бис листа:
Defile Recommended Stat Priority: Strength = Bonus Armour > Mastery > Multistrike = Crit = Vers >> Haste
Hellfire Citadel 'Defile BiS' List
This list is oriented towards using Defile (not much focus on Multistrike), and is biased towards mitigation over DPS, but does not COMPLETELY ignore DPS. I will also give a 2nd BiS list below, oriented towards BoS and DPS at the cost of mitigation. You pretty much cannot use BoS with this gear list as your Multistrike will be too low.
Head: Demongaze Helm (Kromrok)
Neck: World Ender's Gorget (Archimonde)
Shoulders: Doomcrier's Shoulderplates (Archimonde) or Demongaze Pauldrons (Xhul'horac)*
Back: Void Lord's Wizened Cloak (Xhul'horac)
Chest: Demongaze Chestplate (Mannoroth)
Wrists: Wristplate of the Wretched (Shadow Lord Iskar)
Hands: Demongaze Gauntlets (Socrethar the Eternal)
Waist: Annihilan's Waistplate (Mannoroth)
Legs: Demongaze Legplates (Gorefiend)
Feet: Stompers of Brazen Terror (Kilrogg)
Ring: Sanctus, Sigil of the Unbroken (Legendary Quest line)
Ring: Mannoroth's Calcified Eye (Mannoroth) or Zakuun's Signet of Command (Fel Lord Zakuun)
Weapon: Calamity's Edge (Archimonde)
Trinket: Anzu's Cursed Plume (Shadow Lord Iskar)
Trinket: Warlord's Unseeing Eye (Kilrogg) or Reaper's Harvest (Archimonde) or Blast Furnace Door (The Blast Furnace) (Yes really)*
DPS Trinkets (give almost no mitigation, but a lot of DPS, so don't use if you are having survival problems):
Trinket: Empty Drinking Horn (Mannoroth)
Trinket: Discordant Chorus (Fel Lord Zakuun)
*You can also use Chestguard of Ill Fate (Shadow Lord Iskar), or Crimson Throatgrabbers (Kilrogg), or Blastproof Legguards (Hellfire Assault) as offpieces. Or you can even use 3 out of these 4 offpieces and only use 2p, since the 4p isn't that strong. However these offpieces are all a DPS loss over the tier pieces, so only do this if you don't care about DPS.
*Honestly all the 2nd trinket options suck if you don't care about DPS, so unless you cannot stay alive without a 2nd mitigation trinket, I would wear one of the DPS trinket options in the 2nd slot.
Breath of Sindragosa Recommended Stat Priority: Strength = Multistrike = Bonus Armour > Mastery > Crit = Vers > Haste
Hellfire Citadel 'BoS/DPS BiS' List
This BiS list is oriented heavily towards maximizing Breath of Sindragosa and your overall DPS via stacking a lot of multistrike. You can use this list with Defile as well for more DPS at the cost of mitigation, but if you aren't using BoS, swap the weapon for Calamity's Edge.
Head: Casque of Foul Concentration (Socrethar the Eternal)
Neck: World Ender's Gorget (Archimonde)
Shoulders: Demongaze Pauldrons (Xhul'horac)
Back: Void Lord's Wizened Cloak (Xhul'horac)
Chest: Demongaze Chestplate (Mannoroth)
Wrists: Hot-Rolled Iron Bracers (Iron Reaver)
Hands: Gauntlets of Derision (Tyrant Velhari)
Waist: Ravenous Girdle (Gorefiend)
Legs: Legguards of Grievous Consonances (Fel Lord Zakuun) or Demongaze Legplates (Gorefiend)
Feet: Treads of the Defiler (Archimonde)
Ring: Sanctus, Sigil of the Unbroken (Legendary Quest line)
Ring: Zakuun's Signet of Command (Fel Lord Zakuun)
Weapon: Hellrender (Fel Lord Zakuun)
Trinket: Empty Drinking Horn (Mannoroth)*
Trinket: Discordant Chorus (Fel Lord Zakuun)
Alternative trinkets for more mitigation if you can't stay alive with these DPS ones:
Trinket: Anzu's Cursed Plume (Shadow Lord Iskar)
Trinket: Warlord's Unseeing Eye (Kilrogg) or Blast Furnace Door (The Blast Furnace)
+прикладываю различные рассуждения по тринкетам
Anzu's Cursed Plume (Shadow Lord Iskar)
This is the best mitigation trinket in the tier (well Warlords can be SLIGHTLY better in specific situations), and therefore if you plan to use a DPS trinket + mitigation trinket, this is your trinket of choice. Also isn't too bad for raw DPS, but obviously loses to the Burn/Cleave trinkets (below) in that regard. It's high uptime (about 55%) means you can use CDs while this trinket is not up to 'cover' the gaps, and effectively have a 'cooldown' up all the time, which is part of what makes this trinket so strong (but it is the best in terms of raw numbers for mitigation as well).
Warlord's Unseeing Eye (Kilrogg)
Passive haste is very poor for Blood in 6.2, but the secondary effect is quite strong. The problem is that you need to be at low HP, and DKs tend to bounce up and down a lot. This is a good mitigation trinket, but does basically nothing for DPS (this is why Anzu's is better overall). It's exact mitigative value highly depends on the encounter however. One thing to note is that this trinket is very strong in P2 (and Mythic P3) Tyrant Velhari, and since that fight is so unfriendly towards DKs, this means you may want to wear this trinket on that fight specifically.
Imbued Stone Sigil (Kromrok)
This trinket is laughable. It has less stamina then the 685 Pillar of the Earth from Tectus. Now admittedly it has more Vers/BA, but the fact is this trinket doesn't even have ENOUGH stats for it's ilvl. On top of this, stamina is generally poor for DKs. Even if stamina is needed for a specific fight, with the way stamina trinkets are in 6.2, you are literally better off just flasking and gemming stamina instead and using other trinkets.
Tyrant's Decree (Tyrant Velhari)
Oh god. Someone at blizzard must have heard how I said Battering Talisman is the 'worst designed trinket ever', and decided to try to one up it. Let us think about this trinket for a minute; the reason you usually want stamina is because you are being spiked down hard. And if you are being spiked hard, you are probably dropping below 60% pretty often (else it's not really spike damage). Hence you are losing all your stamina stacks from this trinket. So this trinket is a stamina trinket that isn't even good in the normal situation where you would use a stamina trinket. Meaning it literally has no purpose in the game. Why the hell would you want stamina if you are not dropping below 60% HP? And if you are, this trinket does nothing stamina wise. The best part of this trinket is the passive Bonus Armour, and the fact that you can inflate your HP while sitting in town. Never actually use this trinket for raiding.
Reaper's Harvest (Archimonde)
This trinket has good intentions but is just not strong enough numerically. First of all obviously if you are using BoS, don't bother. Secondly, while this trinket looks very strong because it gives a TON of healing, and makes Death Coil hit hard, you have to realize it does literally nothing else. Every other trinket buffs every ability you have (via giving actual stats). In addition, reducing damage is far better then healing it back (ie Warlords/Anzu's actually help prevent damage), as it is VERY easy to overheal with this trinket. Anzu's outperforms this trinket for both mitigation and DPS, and Warlords is better for mitigation. The other problem this trinket has is on 2+ targets, you are naturally using Death Coil less, further making it weaker. The only reason I even recommend this trinket at all is if you want a 2nd mitigative trinket, but are on a fight where Warlord's isn't that great. It can also be good in cases where you have no healer (if they come up in fights). This trinket is overall mediocre even in the best case (1 target, GCD locked, little overhealing) and only gets worse in the non ideal case. It's DPS value is also not that great, and only worse on 2 targets.
*Note on the mechanics; the healing is affected by Resolve and Death Coil multistrikes do proc it, but it does not 'double dip' crit or MS. You will see quite a lot of healing from it, the problem is overhealing and the fact that like said above, it does literally nothing else. Also, this trinket DOES NOT make Multistrike a good mitigation stat even if you are wearing it; first of all you hit GCD lock too easily, second of all Mastery is still way better.
Empty Drinking Horn (Mannoroth) (AKA Burn Trinket)
This trinket does quite a lot of damage*. All your direct damage spells proc it, but multistrikes do not. Diseases/NP/DnD do NOT proc it (DnD might in the future), Defile procs it every tick, BoS procs it every tick (keep in mind BoS replaces Death Coils, so this isn't as strong as it may seem). Note that Improved Blood Presence does increase it's damage by 15%, on top of this because of a Blood DK's high MS, this trinket can actually be stronger in your hands then a DPS players (but it really depends on the specific spec). It's problem is it's mitigative benefit is very limited due to just having passive strength. This trinket is a little weaker on AoE then Single target, but Blood Boil does proc it on every target hit, so it is still pretty effective even on mass AoE. Note that because stacks gained early do more damage then stacks gained later, you want to use Defile at the start of a new stack.
Discordant Chorus (Fel Lord Zakuun) (AKA Cleave Trinket)
Pretty much as above. Again, it is affected by Improved Blood Presence (meaning you make better use of it then some DPS specs do), does a lot of DPS, ect. It is very strong on AoE, but it's range can be a little limited, so you should be careful with how you position (since it pretty much goes off randomly) to make sure you hit as many targets as possible every proc. Like the Burn trinket, it has little mitigative value, so it can be dangerous to equip, but it does a retarded amount of damage even on single target, much less actual AoE.
Rumbling Pebble (Kromrok)
This seems like it would be good for BoS, but the stats on it are simply too low. It is very mediocre for mitigation, and on DPS heavily loses to the Burn and Cleave trinkets, meaning this doesn't really have any use to a Blood DK.
Unending Hunger (Gorefiend)
Like Pebble, this suffers from being generally mediocre. It is the best DPS trinket outside of Burn/Cleave trinkets however, so if they are nerfed, this trinket might become better. It's mitigative value is actually decent, but it is almost all in avoidance, so it can be poor on some fights. This + Anzu's actually isn't that bad of a combination if you aren't using the Burn/Cleave trinkets.
Blast Furnace Door (The Blast Furnace)
Deserves a mention in 6.2, just because the mythic version is better then most of the heroic HFC trinkets, although it loses to the mythic ones for mitigation. Obviously this is a mitigation, not a DPS trinket.
Vial of Convulsive Shadows
Deserves a mention in 6.2, simply because if you lack the Burn and Cleave trinkets, you can use this instead with BoS. However it is not better then those trinkets for BoS, and is useless if you aren't using BoS.
