I agree. Two of our four one-pointers and three of our four Golden traits are integral to Blood right now.
One-Pointers
Mouth of Hell: An extra weapon during DRW, guarantees 10 stacks of Bone Shield per Marrowrend, 25 RP per Heart Strike, and 3 Blood Plagues and 3 stacks of Haemostasis per Blood Boil.
Without this trait, the Blood opener would feel so shit. The 10 stacks of Bone Shield by itself makes this feel really clean, and since the rest of it synergizes so well with our kit it all comes together really well. It finally makes DRW into an actual offensive/defensive CD.
Rattling Bones: 30% chance to generate an extra Bone Shield charge per Marrowrend.
Honestly isn't that important. Quality-of-life, certainly, but not required.
Blood Feast: Heart Strike has 25% Leech.
Pretty shit trait in terms of tuning. Very low actual throughput, I'm not sure I would actually notice if it were removed.
Vampiric Aura: Consumption grants 20% Leech to you and 4 allies for 15 seconds (33% uptime).
Such a useful CD, I feel legitimately powerful when I use this CD, and I feel like I actually contribute to the group with this. The only bad thing about this trait is that the Leech is counted for the other players' healing rather than the BDKs (unlike Warrior's Leech aura), but that's just my scumbag healing parse talking.
Golden Traits
Souldrinker: 50% of overhealing from Death Strike and Consumption increases your max health, up to an extra 30%.
Finally gives BDK the health pool that it was lacking in the previous tiers of this expansion. Gives a defensive benefit for using Death Strike when not actively tanking (outside of Blood Shield), and allows the BDK to have an impressive health pool when they taunt off their OT. The only way to improve this trait would be to just give BDKs 30% extra health baseline, because right now we're pretty squishy on pull if we get unlucky with parries during DRW.
Skeletal Shattering: Bone Shield has a chance equal to your crit chance to absorb an extra 8% damage.
Pretty low throughput, and although it does technically reduce your damage taken, I wouldn't notice or care if it was removed.
Unending Thirst: While Blood Shield is active, you gain 25% Leech and 25% extra damage to Death Strike.
Super impactful trait, it gives us a great boost to our damage and healing during magic-heavy fights where our Mastery is useless, and when we're not actively tanking. The only problem with this trait is that it encourages overhealing with Death Strike (using 2x Death Strike between boss melee attacks), but I do like that we get to choose between offense and defense with it.
Umbilicus Eternus: When Vampiric Blood expires, you gain a shield worth 5x the total damage dealt by Blood Plague
Such a strong talent, this shield can get gigantic during AoE pulls, and because it's a shield and not a heal it helps immensely with our damage smoothing during high-damage points in AoE. Has great synergies with our Legendary chest, and makes BDK feel great with smart uses of Vampiric Blood.
