For a 'Mech as slow as this, a bit of range is never a bad idea. Doesn't use the PPC quirk, but since not everyone likes PPCs, I figured some might appreciate something a little less conventional. The ammo is more than enough for most casual matches, so I considered labeling as an Invasion build; but for Invasion matches, with this 'Mech, I'd really recommend sticking to ERPPCs or ERLLasers.
