Hi guys, I have a noobish Lancer/Dragoon question about low lvl dps. I'm a new 21lvl Lancer and I wanted to know if I play the early levels right.

When I have a tank or the mob is attacking someone else I always try to have my Heavy Thrust buff up and just spam Impulse Drive (with Leg Sweeps and Life Surge whenever I notice I can use them inbetween).
When the mob faces me I just spam True and Vorpal Thrusts. I don't really see see any other combinations for max damage at the moment.

P.S. does my Limit Break gets buffed by Life Surge and Heavy Thrust?
