If you read the patch notes for the latest public test realm build, you might have noticed there is an odd change being applied to priests of the bubbling nature.
Renewed Hope: now has a 60-second duration, up from 20 seconds, but a 20-second cooldown.
Seems a bit strange, doesn't it? Is it a buff, a nerf? What would be the point of adding a cooldown to an ability that has a duration exceeding the cooldown? Well, after kicking the Blizzard downloader all night and day, I've finally tested it for myself and as it currently functions on PTR it appears to have no negative impact on discipline priests. That said, I do not believe it is currently working entirely as Blizzard intends it to. For more information on what I observed, hit the jump.
