in the description of the enrage ability sais it protects characters from stun but my battlerager and Korgan have been stunned twice in the game in enrage mode.its just me? does anybody knows if the patch fix this?

Umm..I dont really have much experience with Berserkers and ENrage, but i dont think it makes the character immune, merely highly resistant. Not fully sure though...

I've had Korgan take on mindflayers with his trusty throwing axe whilst enraged, and they never once managed to stun him.
