Assurance of Consequence, math done.

[Space Troll]

Helpful for people who don't understand how the passive effect works on the trinket. Formula = 100*(1-(1/1.xx)) Note: xx is equal to the percentage shown on the trinket.

Assurance of Consequence - http://ptr.wowhead.com/item=105472

For Assurance of Consequence Heroic and Warforged and upgraded to rank 2. "Increases the cooldown recovery rate of six of your major abilities by 50%."

Formula = 100*(1-(1/1.50)) = 33% cooldown reduction.

Fire Elemental Totem - 5 minutes (300 seconds) cooldown -> 3.33 Minute (200 seconds) cooldown (with glyph on PTR it's 100 second CD)
Earth Elemental Totem - 5 minutes (300 seconds) cooldown -> 3.33 Minute (200 seconds) cooldown
Ascendance - 3 minute (180 seconds) cooldown -> 2 minute (120 seconds) cooldown
Feral Spirit - 2 minute (120 seconds) cooldown -> 1.33 minute (80 seconds) cooldown
Spiritwalker's Grace - 2 minute (120 seconds) cooldown -> 1.33 minute (80 seconds) cooldown
Shamanistic Rage - 1 minute (60 seconds) cooldown -> .66 minute cooldown (40 seconds) cooldown

For Assurance of Consequence LFR and upgraded to rank 2. "Increases the cooldown recovery rate of six of your major abilities by 33%."

Formula = 100*(1-(1/1.33)) = 24.8% cooldown reduction.

just apply the 24.8% (basically 25%) to the base cooldown to see the values. (75, 75, 45, 30, 30, 15 for the lazy folk)

For challenge mode enthusiasts the rate is: Formula = 100*(1-(1/1.17)) = ~14.53% cooldown reduction (approximate values 45, 45, 26, 17, 17, 8.7)

any errors just let me know or changes on the PTR. :3

question is why the hell its sayed 50% if actually its 33% and there is some hiden math involved

Because it's the cooldown recovery rate that's increased by 50%.

Plain as day math. Just most people assume something different if they don't read it closely. Poor choice of wording I guess.

They should just word it as "The cooldown of abilities is reduced by 33%"

Their formulation can get pretty confusing :P
