Pretty good product overall- the Paladin's Armour Divine Bond has me giggling and making character concepts in particular :P
My one complaint- not even really a complaint, just something that I intend to change- is setting-wise how Aasimar and Tieflings are noted as automatically hating each other. That's mostly a holdover from me really liking how Pathfinder reversed that, and mentioned that Aasimar and Tieflings often get along remarkably well, since they both know what it's like to be isolated because of your heritage.
