I haven't picked up my copy of the Pathfinder RPG Core Rules yet (missed my chance to pre-order due to baby and business travelling), but I was going through the PRD and noticed what I am assuming is a big error.
I noticed the Monk's Flurry of blows progression seems way off. Based on the wording of the rules, the monk basically gets a free walk throug the "two weapon fighting" feat tree instead of the old style (where the penalties are reduced at higher levels). However, in the table, the attack bonus for the flurry is all out of whack, eventually ending with a HIGHER bonus when the monk is in a flurry than when he is not.
I'm assuming this is an error in the PRD and not in the actually manual?
