TBC - Armor Penetration

May i ask how much armor has target that is used in simulation?

I noticed, that armor penetration items are quite rare view and since few hours i see quite high priority to choose huge amount of haste items on Retribution.

If i will lower duration by 1 sec to 119 sec, then i may notice even Minor Haste enchant and Iron Counterweight from Vanilla

We are calculating against a boss with 7700 armor.

I can look at the haste stuff… but it looks like the calculation is working correctly. As you get higher and higher stats, getting in an extra attack could become more valuable than a small amount on each attack. I’m guess you’ve found some threshold right where that extra 20 haste gives an extra auto attack in the fight, so it becomes more valuable.
