the fact that the opponent can dispell your buffs with cursed blood via simply existing is fine and all, though as it stands the negatives to cursed blood are less than punishing for the shutdown of vampiric builds and even those who don't even lean into it

-10% status resist is pretty ouchie on san or faith builds, as they may actually want to keep their resist, though for the non summoners/curates who dont build either, or even just build one, it's absolutely free, status resist can be very all or nothing at times, and the difference between 20 and 30 status res doesnt matter all too much when the current skill dumping meta sees people with 140 status infliction on average. The added bonus of lowering enemy status resist on stuff like ghost is neat for them too, so there is further reason to use it with essentially no downside there too.

A build maximising vampiric has to accept for the fact that they wont be retaining any beneficial status effects, though people who just want to use one or two items and not fully lean into vampiric also need to do this (like bards using blood flute). The worst offender here is ruler giving vampiric to other people through seal of labours, which can erase their ruler and other buffs just through hurting other enemies. 

For something that's meant to be a detriment to your blood, it's drawback of -10% status res doesn't really feel that impactful, I think the trait could retain its negative effect of dispelling buffs from vampiric sets, but in turn costing more to use, perhaps something along the lines of -5 vit or -100 or -10% max health for it's user, something that would genuinely come from cursed blood. such a downside could help with the issue of people just using it for statistical benefit due to how free it is and keep it more in line to being used by characters who's body is actually suffering from some dark force.
