Dark intent giving different amount of haste.

[SoulJnr]

Logged on today checking my stats, when I come across my haste with and without dark intent.
Without dark intent - 2104 (+16.43%) - 17.59% total haste
With dark intent - 2104 (+16.43%) - 21.12% total haste

This gives a total of 3.53% haste from dark intent, I have no other buffs at the moment except from fel armour, flask of the north and savory deviate delight. Did I miss something, I really don't get what is going on, either i'm doing something wrong, my UI is bugging out or that something odd is abroad.
thanks.

But where is the 0.53% haste coming from?

No error, that's just how haste works. Haste gained from different sources stacks multiplicatively.

In your first screenshot, you have 17.59% haste total, 16.43% of which comes from haste rating. I assume you're getting 1% haste from another source. If you are, then you have 16.43% haste from haste rating, 1% haste from another source, and your total taste would be:

1.1643 (haste rating) * 1.01 (other) = 1.175943 (total haste, displayed on your sheet as 17.59%)

Now, we add in 3% from dark intent:

1.1643 (haste rating) * 1.01 (other) * 1.03 (DI) = 1.21122129, or 21.12% haste.

Edit: For the record, if you were to then get the 5% haste aura from a spriest or moonkin, your total haste would be:

1.1643 (haste rating) * 1.01 (other) * 1.03 (DI) * 1.05 (haste aura) = 1.2717823545, or 27.18% haste

1% from goblin passive, i see where i get it now thanks.

no worries.... figures though, I can calculate haste but I can't notice that you're a goblin. That's just the sort of mistake I typically make :-P
