By the way, reading through Methu's upgrades, I get the feeling with the talk of an extra granted melee attack that the granted power is actually supposed to be more like the Whirling Frenzy (http://www.d20srd.org/srd/variant/classes/classFeatureVariants.htm#rageVariantWhirlingFrenzy) Barbarian ACF from Unearthed Arcana, rather than the Frenzied Berserker?  The Frenzied Berserker is basically just an added boost on top of normal rage bonuses, after all. ^^;
