NPCs assisting PCs

[Malrubius]

I'm not sure about this one - but in Classic, I seem to recall Guards assisting you (the player) if you got attacked by another mob that was NOT normally kos to the Guards. IF you had better faction with the Guards than the other mob.

This was true with non-Guards as well, iirc.


Example...

You are Ally with Mob A.
You are KoS with Mob B.
Mob A and Mob B are *anything less than Ally* with each other (let's say they're Indifferent to each other) - so they won't normally fight each other.

If Mob B attacks you, then Mob A would attack Mob B (since Mob A is your ally).

Do I have this right? I see situations here that this does not happen. I can list specifics if my assumption above is correct.
