all opinions welcomed on these sets based on a pvp point of view
pvp blood spawn is better, pve bloodspawn is better. in all regards bloodspawn beats bone pirate. you need that healing or your really just screwed. plus bloodspawn gives you plenty of armor and ultimate generation compared to bone pirate.
I've used both in PvP and found Blood spawn to be better in terms of survival and resource managing, the ulti boost is great on my DK and feels more tanky too. Also I find the lack of healing in skeleton form too much in order for me to use it compared to blood spawn.
imo blood spawn with vampirism is good and pirate is better than bloodspawn without vampirism. when pirate proc you have like 30% more tanking, its equal to 19800 mitigation...if you have a correct healing run bone pirate (nice with orc race), if you have low heal and need more sustain, run bloodspawn.
Pirate without vampirism as someone has said. You can easily hit 1-2k health regen without sacrificing too much and it’s basically a constant HoT. If you’re a vamp—as 90% of the pop are—then Bloodspawn.
Also Pirate + Jorvuld’s = perma protection. The healing debuff is easily eliminated by heavy armor/Argonian/CP/ritual and the good news is that you can’t be further defiled (minor/fasalla’s) while it’s up.
Basically any sustain build should be able to outheal a defile in PVP anyway or you’re in trouble.
