I think balancing feats do make it a near tossup.. but once you add 1/2 BPS and maybe 1 less AC, maybe 2 more Hp... then again not necessarily, if you ARE doing a +4 CON --- then you are talking about 3 mor HP ( potentially effectively 6 more). Also, you are now tied AC... So better base endurance stats, but no spell that will add 1-4 effective AC... but likely a mound of HP. The variable AC boost applies to all attacks.. which is why I feel the fighter clearly wins on low level enemy groups... but low level bosses (although lv 1) still are more likely to overcome a variable high AC, while a

of effective HP, while still being hard to hit, still favors the barb IMO. Still close to a toss up depending on variance of build and rolls
