What you're asking is, in essence, "are the Hojo Hordes still there in M2 ?" .

And the answer is : not always, no, and even less so on VH when their prime directive is to attack YOU like so many zombies ("plaaaayeeeeeeer !"), but I've seen it happen. Most often with Poland, Milan, or allies I've been pumping with cash to keep them off my back, only to have them turn on me much later, when they've got half the fog of war
