As above, this quest caused me to stop playing my level 11 Norn warrior and re-roll another race / class after innumerable deaths.
I don’t play a lot of MMO’s, generally I don’t enjoy them. I do know broken quests though and the leveling back of your character means this is supposed to be run solo. I don’t think it’s possible without a stack of grinding to level your character and gear, something that GW2 wasn’t supposed to require.
