Its bugged boyz although since the effect starts 10 yards away it will still affect targets IN FRONT of you and if you not sitting in the middle of the hitbox. Try turn around and shoot a DS. Last night u would not get damage from it (although u should since it is supposed to cycle around you initially). Not tested last 14 hours maybe its fixed.
On a sidenote with crusade for ST, BoW talent pushed clearly ahead of DH and actually with a crit rate of 28% and trinkets that can procc crit BoJ comes on par if not better than DH (crusade ST) as well ..... interesting.
And with the haste levels and the concominant BoW proccs achieved during crusade I don't see DP getting near (especially if your dps legs are belt and ring --- perfect synergy for wings cd).
Thanks for nothing blizz
