You could abuse the system and create a Human/Nosferatu Adept or Ork/Wendigo Adept. A GM likely wouldn't allow it (because it is abusing a loophole) but, by one reading of the rules, you then end up with a Mystic Adept with full power points for only the karma cost of Adept (and you get Nosferatu or Wendigo for 10 less karma). The wording of the "point buy" section should have been clarified as there are all kinds of problems with it (most of which can be worked out by applying some common sense).
