Using Carnutes against Agarthans sounds like trying to beat Agarthans at their own game. Of course high strength helps to punch through armor, and with berserk on it could be even worse, because in this particular case (C. Nobles) it substracts 2 from defence. You're basically trying to say 'Carnute Nobles are bigger, stronger and tougher than Agarthans'
I'd rather try Ambibate Nobles who have +6 defence compared to berserked Carnute Nobles, and a bit more attack, too.
