Very simple use. Poke with your LPL, blast with your MRM60, buff damages with your right side. I prefer put the 2 LPLas in the left arm for benefits the very hight mounted hardpoint. If you prefer put it in the center torso to avoid left side lost, it's your choice. MRM and LPL synergise very well with similare optimal range. Under 450m you are fully operational. For the cool down it's not so bad, you can torse twist and fire every 4 sec.
