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

Except that they tend to get ganged up, since they're perceived as unbalanced.

And given the perception of early game strength and late game weakness, I'm not certain, as I said above, that a nation that bumps off 2-3 neighbors and then is brought down when its strengths no longer apply is really balanced.

Finally, and somewhat tongue in cheek, that's not a statistically significant sample. Given the number of nations, even if Vanheim was twice as likely to win as any other nation, the observed distribution would not be unlikely.
