An escalated version of 15xcHSL piranha https://mech.nav-alpha.com/#a7ab7a0d_HLF-B Barely capable of sustaining one alpha strike without overheating (99% heat without skills, according to MechDB), simply run around the map avoiding any contact and while keeping an eye on the map. Once you spot a lone target, flank him, hugh him from behind and whisper... OMAE WA MOU SHINDEIRU MASC should be used for those moment when higher speed is needed, e.g. closing in or GTFO 'cause those asocials don't like being hugged. Due to the fact I don't own the mech, I can't test this build. If you manage to overheat with a single alpha strike, maybe drop that half ton of ammo, strip some armor and fit another DHS.
