I put together a (soon-to-be) Frenzied Berserker.
Barbarian 1//Feat Rogue 1 - Lion Totem, Toughness (FRB), Troll Blooded (HB), Destructive Rage (L1)
Barbarian 2//Monk 1 - Wolf Totem (Improved Trip), Power Attack (MB)
Fighter 1//Feat Rogue 2 - Cleave (FB), Endurance (FRB), Intimidating Rage (L3)
Fighter 2//Monk 2 - Improved Bull Rush (MB), Open Fighter
I know Monk was banned for flavor reasons, but I really only took it because the Overwhelming Attack variant gets Power Attack and Improved Bull Rush as bonus feats, which are both necessary.
The plan is to go one more level of anything (Ranger?), then one of Horizon Walker, then Frenzied Berserker. Not sure what would go on the other side though... Duskblade, Dread Necro, or Beguiler, probably.
The concept is basically one of Odin's Úlfheðinn. I'd be wearing little to no armor, raging, and smashing ALL the things!
