IMO the shield spec is way too squishy for the amount of damage you lose sub level 50. I'm assuming this all changes eventually, and it's quite easy to top the dps chart in a warzone because VG's sustained dps is fantastic. Go hover over your damage though and see that your 2.5k high crit pales in comparison to the 4k+ that real dps classes dish out. If bioware would just make a level 50 bracket we wouldn't be having so many issues anyway because once you hit 50 it's a whole new ballgame.
