Hoarder Vampire and Warmonger Gorgon are the two worst, IMO. The inability to convert basically wipes out the entire reason to play Vampire in the first place, but you're still stuck with all the downsides. Warmonger Gorgon has the obvious problem that you can easily get yourself stuck. A bear mace preparation is mandatory and you'll probably still end up getting stuck if you don't worship Binlor, which is nasty for a warmonger.
Specialist Sorcerer and Half-Dragon are annoying (since their main attack has a physical and magical component) but can be circumvented.
Isn't Warmonger Gorgon mostly defanged by bringing a Titan Guitar? Vampire Hoarder sounds godawful, though. I think you'd have to either devote the entire run to a huge spike on the boss at level 5 or so, or go pure spellcaster and happen to find everything you need.

Is that still in place? I thought the devs actually shut that one off. I don't have the Titan Guitar lockered and the item works completely differently when prepped, so I'm kinda blind to anything regarding it.
