Based on previous posts, by both players and Kodius, it appears we (barbarians) need at least one IF booster, namely Powermonger or Duelist. Powermonger would provide a bigger tank to put the fire in to and Duelist would provide a way to turn blood into more fire. Suffice it to say, it seems pretty wonky that you need one of those two masteries to max out a barbarians potential both from a role playing and a mechanics perspective. Am I wrong? (Don't answer that except in regards to my post cause I know I'm "wrong"!)
