I'd drop some comments, but I don't intend to make you change your mind
(Also lots of game material there which I really don't know about.)
- Bluff as class skill for Fighters but only with some uses. I'm not sure what you mean here. If you mean that a Fighter who spent 4 sp in Bluff counts as having +4 for feinting in combat AND +2 for other uses, then it's ok. I had the doubt that you meant he'd have 0 in the other uses, but that would be unfair.
- Feats for Xp cost. Lots of gamers consider metagame feats weak, why do have them cost triple? I think metamagic are fantastic for spontaneous casters, for other casters they are costly feats.
- Critical rolls: without a confirmation roll, criticals will depend ONLY on the weapons, and not on the characters.
- giant elves?
