Not necesarily. My biggest complain is that we're supposed to be the Black-Ops of our Factions, the people who do the dirty work while operating in the shadows and trying to maintain plausible deniability. I've always advocated that the Combined Army should be part ot the Cloak and Dagger Narrative. Instead of the flash and bang of "we're here to conquer you," they should be working as insidiously as we should. There is merit in grouping factions into uneasy alliances; like, and this is just a hypothetical example and nothing more, Haqqislam and Shasworth Financial sending forces to disrupt a PanO Company for completely different reasons. So you get Combined and Haqq vs PanO without Haqq working with Combined by fluff (but for campaign purposes, they are). For O-12 I'd use this campaign as an example. Haqqislam wants control of the Battery, but it's guarded by Ariadna and O-12. All of our fights should be translated to: Haqq is secretly sabotaging the Battery, Ariadna and O-12 are trying to stop them and since "Dead Men tell no tale" our encounters are rather lethal. But Haqqislam will deny any presence at the battery and Ariadna will never accept their defenses have been breached. We can have communiques between Faction representatives (calling each other out and making threats) but all of us knowing that the Politicians that are the facers of our Factions will still smile at each other and converse on the matter while having a Diplomatic Meeting with fine wine and steak.
