The Roiders definitely have a set of very useful fighters, my absolute favorite being the Dragline. For 15 OP, you get 2 infinite ammo Annihilator Rocket Pods with damn good suppressive effect for anything too slow or too occupied to escape, and 4 mini-Sharpshooters that provide a damn good PD screen as they've also got IPDAI built in. They're also very tanky in their own right, so they can take hits for you when you vent and not get shot down. Slap that on a Mora, along with a couple Rocksaws, and you've got a ridiculously good knife-fighting battle-Mora - if it can't escape the rockets, it can't escape the Mora.
Come to think of it, I'm surprised the Roiders never made their own version of the Mora - it's definitely right up their alley mechnically, functionally, and lore-wise. I can't imagine them not slapping some MIDAS armor modules on it to make it yet more tanky.
