This. Remember, guys, skills in this game were designed like this: 1) Think of a mechanic the tree can be designed around (Battlefield control, Artifacts, Quadratic leveling) 2) Think of a theme that fits the mechanics (Golems, Archaeology, Meteorology) 3) If you've still got space, add some stuff that fits the theme more than the mechanics (Bees, Birds, Meatballs) The mechanic comes before the theme, and for vampires the mechanic is "heals by stealing life, and only by stealing life". Therefore, even if it fits vampire lore, vampires should not get regeneration, but they could gain resistances if you like. Though do keep in mind, there aren't actually that many sources of elemental damage in this game. Asphyxiative, for example, shows up from potatoes, and not much else.
