My character Liebling on Mischief looted a Mark of Valdeholm and clicked it last night. Today I tried going into Frostcrypt 1 raid, because I was told the Mark of Valdeholm would back flag me, but I was unable to zone in. I kept being kicked to the zone line with a message I did not meet requirements.
Per allakhazam: "Still need the faction, the 3 fergarin group tasks, and the kanguar and Udengar raid tasks to be fc1 flagged."
