instead of putting on shield which takes away dps, put 6 on the crit one. im a level 41 com so dont worry i know what this is. and put neutronic stomp at 1 its just to knock down.
at level 41, i use Force hammer-6, Neutronic stomp-1 its just to push down, Singularity-6,Vigor-5, Graviton slam-6 gives 70% slower speed when it hits, kinetic resevoir-6, Rage-6 Very important!!!!!, Back breaker-6
BTW use neutronic stomp or singularity and then use back breaker to make a combo which means extra damage
