I would call it a Trap spec.
Pretty much i have ran this build up from normal to Inferno without any real drama, the trap damage at present is huge damage output and burst.
see how you like it. its simple to use with no worries with melle classes jumping you.
Rotation would be as follows for both situations
1) boss single target - Calt x 6, Spikes x 6, bola, bola, Rapid Rince repeat work of your hatred and discipline to create some devastating damage.
1) Multi target - Calt x 6, Spikes x 6, Bola x 2, Multishot x 1. Rince repeat
Works like a charm. when played perfect you will not get hit.
