Well, in fairness, Ariadna are one of the four factions to have more than one Dire Foe character now. CA have three, Ariadna two, PanO two, Haqqislam two. Everyone else has one, except the NA2 mercs. YuJing used to have two, but now she's JSA. ALEPH/Ariadna would make a lot of sense right now though. You then have Tohaa, Nomads, YuJing, Druze, Ikari, and StarCo left. You simply have the Druze one viable for Haqq (maybe in Khanate or Ramah) to bring them up to three, the YuJing one works for Ikari as well as Invincible Army, and the StarCo works for Bakunin or Tunguska as well. Easy setups too: Tohaa distrusted by one of the other three, One of them opts to send their shady little part-time merc in. The leftovers, well, they're mercs, they have ample excuse to fight each other. Say it's DruzeHaqq vs Tohaa, the StarCo-Ikari rivalry steps up. Now all NA2 have one, the major factions have at least two, Haqq joining the three-DF club. Almost every sectorial has at least one too: only Acon and Varuna, MRRF, and Bakunin or Tunguska lack one, in only three more Dire Foes sets.
