At first glance, a big disappointement, useless classes, unnecessary powers, unbalanced capacities or abilities, and a really, really ridiculous behaviour predictable from the cavalier when he will issued his oaths or challenges...
Be careful of the "WotC" virus : new books, new classes, new powers, no role play interest, no balance... I'm not sure Pathfinder RPG must evolve like the 4th ed or WOW...
