Is it just me, or does the Berserker completely obviate the Veteran? I can't find anything that Veteran's get that Berserker's don't also get. I guess the fluff is different, but there's a pretty huge power disparity.
That's probably a bit extreme, you might want about 10 tricks for other things so that you can slaughter people more effectively while in Berserkerganger. Maybe, Combat Coup, Speed of Sound, Speed of Light, Combat Maneuver Master, Sudden Movement, Iron Mind, Killing Blow, Heroic Killing Blow, Full Attacker and Incorporeal Bane. Maybe replace one of those out for Lifeburst or Healing Hands so you can so you can heal up after the fact. That leaves 40 tricks for constitution bonuses, for 2390 hp, for an average of 34 rounds of being an invulnerable death machine.
Oh, and I'd just like to mention how impressed I am at Jormengand's prodigious homebrew speed.
