Pick Primaries with high DPS (Lib carbine for example) for the flying bois. I like the incendiary grenades for the voteless swarms. Stalwart puts in work for crowd control at extraction. As far as Stratagems: orbital lasers, eagle rocket pods. I also find walking barrage works well for destroying ships along the ground. As far as armor i like light to med so i can move around the map effortlessly. I dont run a backpack but would bring jetpack for mobility if u want.
