https://mwo.nav-alpha.com/mechlab?b=cae9e2e9_DWF-UV Lost the original smurfy. Reworked with 2xMPL. Not cool enough for prolonged brawling, but still scary at short ranges or if armor is stripped. Slight reduction on heat and cool down in the July 17 patch. Most of the weapons still will be ready on a 4 second recycle period. So twist and plan movement accordingly. After an initial opening, you will likely have to rely on the LBXs until you can cool down. If you want to go cooler, you can trade out the laser or downgrade the uac20 for more ammo or heat sinks. See the original Ludwig build.
