Can't say I'm completely happy with this build, but I've tried 4 of the more popular loadouts and never really liked them. 3+LL never seemed to do the dmg I think they should, I have an aversion to SRMs because of hit detection, and streaks make me sad. So, that leaves this... PPCs and 2JJ for poptart action, lrm5's (chainfire) for annoyance and to keep you fighting while you're looking for the next ppc target or indirect fire, ML for either a close combat last resort or the last little bit of punch you need to pop an enemy side torso.
I ran a similar build for a while - got tired of being lunch for lights. 2ML not enough to defend yourself in close :whacko:
