[HF] seems to have more activity than some other official factions that remain official. Though if the faction and it's leadership feels things aren't going anywhere and is out of options how to fix it, it's all in their right to disband gracefully rather than wait for the inevitable "Faction no longer official" that would happen eventually. If none of the resources and props go away this is also a decent opportunity for anyone interested in shaping their own Hellfire Legion faction to come forward and do their thing.
After all - if you're holding officialdom just for the sake of officialdom, you're obviously doing something wrong, at least in my eyes.
GL to Justin and Co. in their future endeavors around here!
