Random Faction Question

[loramin]

Is there a way to tell which faction is a mob's "main" faction?

For instance, let's say I kill Guard Bixby in Qeynos Hills; I'll get the following faction hits:

• Antonius Bayle (-30)
• Guards of Qeynos (-30)
• Merchants of Qeynos (-30)

Now let's say my Antonius Bayle and Guards of Qeynos of factions are maxxed, but my Merchants of Qeynos faction is rock bottom: as I understand it Bixby won't attack me when he respawns, because "Merchants of Qeynos" isn't his "main" faction.

If that's correct is there any way to determine what Bixby's "main" faction is? For Bixby I would assume it's "Guards of Qeynos", but for all I know it could be "Antonious Bayle", and for plenty of other mobs it's even less clear.
