hmm... Rogues are good for activating TF-traps or gettin snatched up as vore prey... or usin' poisons to paralyze someone to easily gobble them down. Healers make really good prey in vore (but i love them as preds too, eheh . ///.), or TF causers... I feel like there's something for wizards and spellcaster mages too but I'm not sure what exactly!!

I'd have to say hottest is healer but i'm biased because i have a healthbar kink and i think i have a healer kink also
