I like the combination of MRM+ML, and on this mech with missile cooldown -20%, energy range +10%, and energy cooldown -10% this works really well. Both arms are empty, but even without added armor they have 14 points due to quirks (+3 with full armor skills) to be used for shielding. Quirks and skills add up to a bonus of 177 points of armor! If you want to go zombie with the two belly-mounted medium lasers, you can get this by dropping one ton of ammo, a slightly slower engine and only losing few points of leg armor, but weapons and cooling are still the same: My skill tree: https://kitlaan.gitlab.io/mwoskill/?p=jsonbin1.5a2852a9fd477e69d2bcf91c You can easily exchange some range, velocity or heat gen for a shorter cooldown, but the MRMs already fire fast enough due to the missile quirk. Weapon groups: 1: both ML 2: MRM40+MRM20 (with a small penalty of 1.61 points ghost heat) 3: MRM40 (for maximum damage per heat)
