Oh but thanks I really like the feel of that! Grappling for a vampire seems extremely thematically appropriate. The idea of a stalking Undead hunter who runs up and strangles Vampires to their re-death, literally killing those who cursed him with his own bare hands. Seems really, really nice.
EDIT: I'll probably change out the Nemesis feat for that feat that improved Skirmish damage (+2d6 for every 20 ft. or something) since this character is far from Exalted
EDIT2: I realized that your build didn't actually have Swift Hunter
