For those who were wondering, I use the build http://www.torhead.com/skill-calc#200bZhGMRkMR0zZf0cRrMz.1
I use surging charge as a filler since I sometimes do flashpoints, other than that I stay in Dark Charge for pvp, keep a shield in my offhand, and go half tank gear/dps gear.
This build has decent survivability with Dark Charge active, and tons of control on the battlefield. Instant whirlwind with a stun, a 4 second incapacitate, 30% aoe damage reduction, burst from maul, shock, and death field.
I will prob switch discharge 2/2 over to avoidance 2/2.
