Ok i got this idea today you can get the hakkar faction for additional 20 people if it works... Simply Get them in front of hakkar and let them logout. Then take hakkar down to like 15-10% and tell those who are offline to get online. Then kill hakkar before they are auto teleportet. Of course they have to help you kill hakkar... So they should get faction and should be able to obtain loot...
Wanted to test it today but our GroupDPS was so insane... I didnt made it in time to log into my second account what a pitty but i will keep on trying^^
