Utgarde Keep

I don't know if this is happening to everyone, but this achievement is not showing up under Dungeons and raids -> Lich King Dungeon. The heroic version of this achievement is there, but not this regular version. So I went to Dungeons and raids -> Northrend Dungeonmaster and it was properly displayed as completed.

I just soloed this as a level 82 fury warrior (with greens & blues ilvl 278). Didn't have much problem at all, only used 4 health potions & maybe 6 heavy frostweave bandages. Popped commanding shout or battle shout before each encounter. Prince Keleseth ice bound me once, after that he died pretty quick. The hardest fight was probably Skarvald & Dalron. I targeted Dalron 1st & concentrated on him. Ingvar was not too hard but after you kill him the battle god resurrects him so just remember to use health potion or bandage in between. In the mob fights I always concentrated on casters/healers 1st.
