I feel like the devs got lazy when it comes to the passive traits. I'm completely in favor of removing all the passives. However, instead of increasing the cooldowns to a ridiculously long five minutes (300 seconds), why not change the trait completely. For example, instead of Defy Pain granting Lesser Endure Pain when the player is struck while below 50% health, how about granting protection for 4 seconds. That would significantly reduce the strength of the trait but wouldn't make it totally useless for five minutes.
