This build actually came about, believe it or not, from me trying to mitigate my heat issues with the BJ-3. My main build is a variant of the Laserman (1xERLLas, 1xLLas, 4xMLs, AMS, 3xJJs, XL235) which fires the large laser and the 4x medium lasers when in brawling range. That's 23 heat a pop. In the same range this mech fires off its large pulse laser and its 3 medium lasers for 20.5 heat and has an additional heatsink. So, the heat issue is improved and its better at light hunting while giving up some DPS. The main benefit to this mech is that in brawling range it can jump and twist a lot and still keep up your damage due to all of the pulses. It sure is a rush and a very different way to play this mech! In full disclosure, I was only able to put up 250-300 damage consistently from this mech and had a hard time swinging matches in my team's favor. I tried all afternoon on it - it's a very difficult mech to play. Definitely a pro build as the BJ is so fragile at brawling range! I'm hoping there's some pilot out there much better than me that can really make this mech shine.
