This was my first build on a Firestarter (until I moved on to 6ML) and it performed well. Great heat efficiency, low firing duration and decent DPS. It is essentially equivalent to a 4MPL build. The only drawback (other than low alpha) is DAT RANGE. I am hoping that SLs get a range buff to 135 or even 180. If any build is going to try and make SLs viable, it is this one.
