PC NPC PC

One of the driver of AW was the triangle pc-npc-pc
In AWDA the PCs seems to be more on one side. The oath system strengthens the bonds between them instead of create antagonism. Is still useful to build this kind of triangles or could be against the approach of the game?

I'm of the opinion that ALL games that have NPCs need the PC-NPC-PC triangles to have those NPCs be interesting.

PC - Location/Holding/Interest - NPC

I definitely don't see this as a problem. Let's say a PC has an important NPC ally. That NPC and a PC hate each other's guts. That's more of a pickle for the first player if he is working with the second PC - if they are at each other's throats, it's just a pretext for having it out at each other.
