Death vs. Fire bless

[krpeters]

I've been trying out Mictlan recently, and I discovered something odd. Maybe I'm misinterpreting the results, but it seems that a Death-9 bless is more effective on my Eagle Warriors than a Fire-9 bless. I haven't tested it rigorously, but it seems like they cut through enemy troops like butter with the death-9, and only beat up on them a bit with the fire-9.

I did this as an experiment with a "cheap bless" strategy. Taking a MA Prince of Death pretender only costs 364 pts to get to Dominion-10 Death-9, while getting a Fountain to Dominion-10 Fire-9 costs 547 pts, a lot more.

Does it make sense that a 2-AN MR attack would be more effective than an 8-AP attack, especially without the bonus +4 to hit? Note that this is against knights and other heavily armored indys in single-payer, not against chaff (which I imagine fire to be much more effective against) or MP-SCs (high MR would probably stop the Death Weapons easily)
