It's pretty much the same as the old build. It was either bump a thread from 2015 or give it a new one, whatever~ Grab literally all the velocity, cooldown and heatgen skills in the entire Firepower tree. You then have an ERPPC with 2755 m/s velocity and a cooldown of 2.72 seconds. It makes a great harasser or sniper, but an even better brawler. Fast and as long as you're supporting something bigger than you or with a pack of lights, you can do some real damage despite the shitty loadout.
