Went for @enileph 's version and a nice little first battle... right till I ran out of ammo.... 2 kills and 2 assists but our team was rolled over (6 kills total with a DWF getting the other 4) so hard to tell how good the build is. Both sides were massively heavy tonnage (e.g. we had 4 DWF) which didn't help the build. Fun either way - will rate it after a bit when I have some xp on it. 2 kills 9 assists and 325 damage second battle. Ran out of ammo again.
Indeed. 45 ammo is a bit tight. Unfortunately you cannot fit more without taking out FF (I refuse to use SHS). Technically though, SHS might be the solution. If you don't have speedtweak you might have to drop the JJ This, final version.
I tried a similar build on a Firestarter, and a regular AC/10 and an XL180, and it did not go well. Between the slow speed, the low rate of fire, to sweep/scatter damage, I was stuck at around 150-ish damage tops. I think the moral of the story is that you're better off with speed than with backup weapons on highly specialized builds like these.
