Do you allow Power Attack? I’m not sure how well it works with your rules. For instance, an 8th level fighter would take a -3 penalty to attack for +6 damage. That would punch through most armor.
Many of the traditional feats don’t seem compatible. Cleave, Combat Reflexes, Vital Strike, etc. Actually I’m not sure which feats to allow and which to disallow. Or should I just use yours?
