Is the Oracles and Frenzyheart Tribe facion change bugged?

Hello, so I'm playing on IceCrown and I want too grind The Oracles rep but I cant because I'm on the Frenzyheart Tribe side right now. I have read that you can change sides by killing Artruis the Heartless. While you are in combat, Artruis will freeze at 30% health and two counterparts will emerge from their frozen state. Killing Zepik first will ensure your allegiance to The Oracles, while killing Jaloot deters you away from The Oracles. When I kill Zepik Jaloot should give me a quest so I can start the rep farm with the Oracles but instead he only becomes friendly and does not give any quests. Is this a bug or am I doing something wrong?
