THIS spreadsheet, I put in the armor penetration as a stat. And sunder debuff, and curse of recklessness, and faerie fire. So, ideally, you should be able to compair 24 crit rating to 150 armor penetration. I have the dps adjusted to armor mitigation based on armor values of the mob.
Say on most boss mobs they have 7700 armor (this is a generalization).
RPZip already posted something like this earlier, maybe I'll find it later and quote them (him her? can't tell). But 150 armor pen is a variable amount of dps boost, just like crit.
the more you have of armor pen, the better it works for you.
So stacking armor pen is actually a VERY nice way to increase personal DPS.
With 3690 armor (7700 - 5x sunder, CoR, FF) a lvl 73 mob has 23.58% mitigation.
With 3540 armor, 22.08%
A 1.5% increase.
But if you stack roughly 500 or 1000 armor pen, you get way more out of each 100 you stack.
At 300 armor pen, 20.53% mitigation; 1.55% increase on dps (from 150 armor pen)
At 450 armor pen, 18.92%, 1.61% increase (from 300 ap)
600 AP, 17.23%, 1.69% (from 450 ap)
750, 15.48%, 1.75% (from 600)
and so on and so on.
24 Crit rating ~ 1.09% crit?
So your looking at an increase from 150 armor pen being higher than 24 crit rating, generally.
These values are just generalizations, some mobs have higher mitigation, and others have less.
