Is it just me or is Hellheim troops way to strong?

We're beating a dead horse IMHO.
The combo of 20 def+glamour+fast+sacred+low res cost for a paltry 75 gold is a magnet for a high level bless (F9W9+)leading to a very unbalanced nation.
I've yet to find a way of countering Vanheim or Helheim before turn 25+ (if still alive). Last try was Arco vs Vanheim MA (F9W9N4), I get stomped and neither Elephants nor groups of astral mages scripted to Mind Burn and Paralyze had even marginal efficiency (considering battles opposing somewhat equal cost of troops).
Maybe Fire magic is more effective but I'm don't think it's enough before level 5.
When playing Vanheim the hardest fight I've had was against Machakan big sacred Black Hunters spiders (which had a F9N4 bless). But even then I beat them because they are much harder to produce en masse so they were overwhelmed (I had 80-some vans vs 30-35 spiders, because spiders cost 66% gold and 200% res MORE than a Van).
Worst thing is that when you lose you don't even have survivors as the ultra fast Vans wreak havoc in the rear...
