I am getting strange results (like I always have) again with this release.
I am using 16/0/55 -
Talent Calculator - World of Warcraft
I am using a rotation, not a priority, it has not changed from the default unholy rotation you supplied.
<?xml version="1.0"?>
<Rotation>
<Rotation>
<PlagueStrike retry='1'></PlagueStrike>
<IcyTouch retry='1'></IcyTouch>
<ScourgeStrike retry='1'></ScourgeStrike>
<BloodStrike retry='1'></BloodStrike>
<BloodStrike retry='1'></BloodStrike>
<DeathCoil retry='0'></DeathCoil>
<DeathCoil retry='0'></DeathCoil>
</Rotation>
<Runes>
<Blood></Blood>
<Blood></Blood>
<Frost></Frost>
<Frost></Frost>
<Unholy></Unholy>
<Unholy></Unholy>
</Runes>
</Rotation>
And I am using the following character sheet (enabled 4pc for future gearing efforts, not because I use it atm):

<?xml version="1.0"?>

I got the following values in a 1000h sim:

Any clue what is going on? Obviously weapon dps should be significantly higher on the EP scale (2.5x or higher?) and armor penetration is definitely not worthless when I am using a set rotation using BS and when the bulk of my damage is white damage. Similar issues occur with blood - I get abnormal haste values, and sometimes expertise values.
