Basically an orion with higher hardpoints and less survivability. Equip a DHS instead of 1t of SRM ammo if you have it skilled out with missile rack, or just because you die a lot before spending it all. It makes it 100% slot efficient, and helps out pretty well with the heat this build can generate.
Definitely another I need to try. I've been enjoying the LBX-10 on the 4P in a brawler configuration. This seems like a good evolution.
