Cool! I completely forgot to test it out of zone, while healing PoF last night I was trying to pay attention but did not see it proc anything, I was casting it ALOT as well; 3 chokers in group. Thanks for the verification.
I've been boxing an SK - it procs a fairly good size bunch of heals if the target is using power - so I cast it, then use all the nuke/debuffs an SK has. If you time it right, it's pretty nice.
