Totally agree, it depends if u got a tank guarding you, if so Kolto Shell them, Or the ball carrier in huttball if not shell your self before anything, this can heal if not mistaken up to 3-4k, also if you are self healing, use the Cure ability, it heals a bit and removes any pesky dots, it takes off so much heat if your getting pounded by multipe Dots. And dont forget to Kolto Bomb a lot, i use this more than rapid scan as it makes us more mobile. Also when u need a breather Knock back, then powersurge with thermy override to rapid scan and run like mad while kolto bombing and curing. IMO they are fine just gotta play it right.
