If you'll look at original topic it was mentioned on -
Berserker redesign - it was supposed to be something similar to berserk, but related to wolf instead of bear. Right now I am in the middle of quite huge update pack, which includes berserker rebalance:
Berserk power 20->7 (heal ability was removed earlier as a bug), his ability has additional +13 power, +1 power range (area attack), +200% mental resistance, +100% hp, but -100% bonus healing (cannot be healed in berserk state), -2 sight. Additionally he is healed by coming into berserk state (+10 hp heal). Ability lasts 4 turns and has 7 turn cooldown.
Looking at that and trying to make wolf warrior 3 turns I would make stats:
17 hp
1/1 armor (dodge - armor doesn't really need to represent real armor - it's just amount of power reduced from attacks each time, so something stable - really strong armor, ability to dodge thanks to training etc.)
7 power
3 speed
100% mental resistance
and ability Rage 4 turns, 7 cooldown:
+3 power
+1 action
+1 speed
+3/3 armor
-100% bonus healing
+200% mental resistance
-1 sight
and similarly 10 hp heal effect on use.
