Something more pinpoint that makes use of the cooldown and duration quirks. It should be really hot, but it should be worth it. EDIT: yup, too hot without skills, not worth it without skills.
I'd want more speed, and more pinpoint. The loyalty mech isn't in Smurfy or the phone app, so pretend that the UAC is in the torso, like yours. Also pretend the MRM launcher is a SNPPC and DHS (or TC, or a ton of UAC10 ammo)
IMHO it's not worth it: LPLs generate less heat, they have better range, better cooldown and thanks to the mech's quirks already have 0.5s duration, which is not very low, but still very good considering they deal 10 damage. Also, the UAC10 alone is kinda hot, which further reduce the effectiveness of this mech if you ever happen to brawl. My previous 2xLBX10 + 2xSNPPCs was already hot, with 3xSNPPCs it will become unplayable (plus the risk of facing ghost-heat) and will probably have too short range and bad hardpoints to be an effective poker. EDIT: I've abandoned the idea behind this build. I could pick it up later once I finish skilling and mastering this mech.
