Mech is not available on smurphy ATM 6xMG, 1xMPL, 1xSPL, LAMS, 1xJJ, XL255, 2 tons of ammo, full armor Be mindful MechDB build is missing left arm hand actuator, so it's a full slot build. MechDB link here Compared to "stock-ish" (2xMPL) there is a small DPS nerf due to swapping a MPL for a SPL, but you gain a LAMS which could prove useful while waiting for a push (small LRM umberella for your poking / long range team mates) or to damp a little the incoming ATMs. Heat should not be a issue.
