7: Hmmm, most of the Vampire's feats are given because it grows stronger and faster. Improved Initiative, Lightning Reflexes, Dodge, Run and Combat Reflexes are all part of the Vampires greater movement and speed. Toughness are part of the Vampires increased stamina. Iron Will is a part of the Vampires enhanced mental provess. The Flyby is a manifestation of the Vampires growing familiarity with being airborne, whereas both Claw Focus and Improved Critical manifest the growing power of the Vampires natural weapons.
The skills are similar in that way too. They are meant to signify the animalistic nature of the Vampire, it's hunter instincts that keeps it aware of it's surroundings.
Thanks for the feedback, glad you liked it.
