Generally if we get absolutely mobbed I tell everybody to run, bang on shield wall and use challenging shout. For the next 10 seconds the mobs tickle me while the others get to a safe distance, then I get murdered.
Also do you know where the quest is for branching off into sword smithing? I read blizzard lowered the requirements to level 45 which I hit last night and I'm at 261 BS skill. I read somewhere the quest is in a instance with a 62 elite boss, if so I may put it off for a while.
