I agree. Too many rules make game play heavy, if I am correctly following Thane. In combat, after attacking, your either passively defending - using your AC and armor and practical defensive moves prevent damage. Actively defending takes additional focus which may take an actual action. Doing some other action or actively trying to do something else like trying to heal someone, hide, or casting a spell. This modality of thinking is similar to the way I was thinking for the Combat Module blog
