I tested this yesterday in RA and its definatley nice there. Basically I used the same thing as the first build of the OP but pump 10 Illu for Distortion instead of EFeast, making the stats 15/10/10.
After making a few adjustments from what I had originally setup, I got 3 glads in a row, so pretty happy about that. Also, it is really impressive sometimes. IE:
-Hit 5 targets for 120 dmg in RA yesterday.
-Faced 3 sins and a monk in TA this morning (w/ a no monk RA team) and asked everyone to ball up initially; they all teled in, atleast 1 had AoD, and there were hexes ofcourse.
I'd probably just switch out BFire for Diversion in TA (though BFire isn't bad in 4v4 situations when you have shatter enchant); also, possibly Empathy for something depending on if we have any other hexes.
