seems like a wash and borderline nerf to me. Lets put it this way:

*not reflective of actual in-game fight dps

15 seconds = 5 gcd (rounded up)

3.0 = 0 proc (0 potency) - 5 proc (1050 potency) rng/bulwark/shelltron reliant

3.1 = 150 potency

still sad to see nothing being addressed on Divine Veil and Clemency. These really needed a bit more tweaking with regards to their in-combat utility.
