Guild Wars 2

The tooltip states that for every point invested in it, the cooldown will go down with 1%.
After aplying 10 points, the cooldown should go down by 10%.
So for example, 10% of 30s (virtue of justice) is 3s. Yes when i go look, the cooldown stays at 30.

Is the traitline bugged? or is it just a tooltip error?

Tooltip error. Use Virtue of justice and it should start the countdown at 27.

Actually, it says “recharge rate” which is NOT the same.

Example: Virtue of Justice is base cooldown of 30s
30% cooldown reduction = 30 * .7 = 21 seconds
30% recharge rate = 30 / 1.3 = 23 seconds

The tooltip still says 30s cooldown, but it recharges in 23 seconds.
