I don't like having more than three weapon groups because limited mousebuttons, so I dropped the engine down from a suggested 325 in another build to a 300 in exchange for more armor and swapping the 2x MLas for a third LLas. Name of the game is soften them up with LRMs and then chop off sections with the LLas and core em with the Gauss. Weapon groupings: 1) Chain-fire LLas 2) Gauss 3) Chain-fire LRM5s
