Faction change Frenzyheart/Oracle

So how do you change faction now between the Frenzyheart and Oracle?

I tried killing the archmage there, where he then becomes immune and you have to side with one to kill the other. but it just ain't working the npc becomes friendly but no quests or any rep change occurs. Am I doing something wrong or is it bugged?

ye did the same i think its bugged, once u pick a side ur stuck with it xD
cant farm both reps. and this is prob not high on prio so no fix soon.

this is bugged ffs.. can't anyone confirm it ?? i wanna change the factions but nothing happens, someone ****in explain !
