The Orc Beserker is a miserably designed sack of hitpoints:
HP 66; Bloodied 33
AC 15; Fortitude 17, Reflex 13, Will 12
Speed 6 (8 while charging)
Greataxe (standard, at-will) Weapon
+8 vs AC; 1d12+5 damage (crit 1d12+17).
Warrior's Surge (standard; usable only while bloodied, encounter) Healing, Weapon
The orc berserker makes a melee basic attack, spends a healing surge, and regains 16 hit points.
Calculating in their warrior's surge (which is a horrible mechanic), they have: 66+16 = 82 HP versus the expected 56 HP or so.
Also, their absurd crit damage is... absurd.
What are some recommended balance modifications to this horrible creature?
