Been going back and farming old Appearances from Legion and not able to get a group together for this, since it requires all 3 players from Same faction and all 3 being warlocks to enter the class hall.
It would be great to get a solo option to be able to farm for this hidden appearance since it’s deader than a doorknob. Spent 3 hours with a custom group up in finder and got 0 bites for it at all.
