80% movement speed reduction?

[Anytime191]

Divine purpose reduces the duration of movement slowing effects by 30% and now toughness by 50%

obviously will be changed but did blizzard realize this?

If you get both it is probably toughness reduces it to 50% duration, and then you get 30% duration of the 50%.
So it'd be like 33% duration on movement impairing effects

I find it hard to believe that they would stack. 80% reduction to a class that already have Hand of Freedom? If anything Toughness would overwrite Divine Purpose, resulting in a 50% movement slowing effect reduction. Just like Crusader Aura cancels out mount speed trinkets. Blizzard just forgot to put it in the tooltip. Though I could be wrong.
