Dec 27th 2008 6:30PM The topic is informative, however I have an issue with the maths you used to come to your conclusion.
That is true that the less armor an enemy has the less of it will be reduced my penetration, but at lower armor levels each point of armomr counts as more damage reduction. This is because armor sufferes from diminishing returns.
Counting that it might be possible that the amaound of damage that armor penetration increases stays roughly the same no matter the armor of the target. I do not have the numbers on that but it would be nice if someone more knowledgeable on the game formulas then me cleared this up.
