I picked it up a few days ago and spend a bunch of time in heroics to see if it has any use at all, I picked it up for the 3% chance to avoid spells but have been finding the 15% run speed to be very useful.

That is my current build, if I get T4 gloves I will drop the 2 points in reckoning and put them in improved judgement again (I do find the 2 second reduction causes sequence problems because consecrate and holy shield have 10 second cooldowns, so the judgement and GD on putting a seal back on end up at off times.)
In heroics the PoJ I find it great for the typical line of sight pull, and also comes in handy when somebody attacks the wrong mob, pulls aggro and runs out of righteous defender range. Even a feared mob can be chased down with easy with the extra 15% speed.
I am sure in raiding it will not stand out in many situations, but my raid is only doing kara and starting into ZA right now so most of my time is in heroics.
