As LC probably noted worldbosses can be encouraged to hit PVP players. Sometimes when this happens I randomly receive honour points, despite not having pvp on.
Its not working consistently, and I mostly don’t get honour from killing LC anyway so I don’t know the exact cause as I can’t replicate it reliably.
I’m playing as a paladin tank, kiting the boss, so I’m probably at the top of the agro table. I don’t know if this is relevant. IV heard about healers also getting honor randomly.
