Get your enemies to run away screaming, "Get away from me you lazy-eyed psycho!" Shorter range and a little more pop than Sgt. Doomsday.
I'm running a similar build, but with standard ML's instead of MPL's, I took it out for a couple games and I like it: _ Better heat management, more speed. The longer cooldown of ML's, AC20, and MRM40 sync better than throwing short cooldown MPL's into the build. You can blast out a respectable alpha strike, then twist and shield, then blast again when everything's ready. Shorter cooldown weapons like LPL, AC10, and MPL mean you end up staring more, letting the enemy core out whatever component of yours they want to shoot at.
