Torque is only good right now due to the huge bonus he gets if you use him and win in PVP. Other than that he is very lackluster.
I have said it in other threads, but the best way to deal with him is totally ignore him. His turrets barely heal anything, they actually heal less than Hardscope’s Drone or Nightingale’s passive platinum heal. The big armor buff and heal come when you kill a turrets. You also can avoid his silver skill by ignoring the turrets and Torque.
So if you ignore the turrets you basically make 3 of his 4 abilities worthless. The small-ish heal (13.5k per second) is barely a tickle. It needs to be increased dramatically so there is an actual choice between killing the turrets and stopping it, or letting it go and not giving the enemy a buff.
