I'll be honest I don't see why these need to be a bloodline, sure Nosfeartu are stereotyped as Count Orlok lookalikes but I believe their disfigurement can be more varied than that. They have Celerity instead of Potence and honestly I don't really understand why. Why only have them allowed to drink coagulated blood?Their organization actually sounds pretty interesting but seems like a choice between isolation, near isolation and what seems to be a nastier/creepier version of the Nosferatu organization.
Well there is some interesting ideas here Gurkhal. They might be really interesting as Nofeartu antiribu, the canon Antriribu aren't really any different to their Camarilla counterparts but these could really fit the bill as some creepier Sabbat Nosfeartu, perhaps they even represent a unique kind of founded pack.
The social stigma comparing to the normal Nosferatu feels forced since corpse-sucking seems to be an advantage (more safe than hunting) rather than a Masquerade breach. I think kool Nosferatu will likely envy such a weakness as the most of them are quite practical and aren't picky.
Depends from world interpretation. From the books, I've got an impression that WoD police are too busy and corrupted for paying attention to disappeared or mutilated corpses, so avoiding being noticed in the process is enough. Otherwise, the existence of vampires would have been uncovered long ago.Of course, if your interpretation is closer to this world in criminal aspect, that's a whole different matter.
As additional touch, a requirement like "cannot feed on people whose deaths they or their brethen had caused, directly or otherwise" in my opinion would emphasise their scavenger (as opposed to the predator) image a little more. Not a physical aversion, like of clan Ventrue, but purely mental, i.e. feeding is possible if the character has no way to know or suspect even in the back of mind.Did not intend it as a gameplay limitation. Some may embrace it as an ethical rule, while more unscrupulous ones would be surely inventing clever ways to circumvent their clan weakness, thus latter could serve as a spice for both styles.
