I'm all for a quest wipe but if it doesn't include winch access it doesn't help me personally much. The only quests I would like to redo are the winch access quests since I got stuck doing the evil side with one of my lawful characters. The other side was bugged and couldn't be completed. I wouldn't care much aside from the fact that which side you use to get into the winch has a huge impact on which quests you can do inside the winch. I believe factions also play a role in quest availability so ideally this should be wiped as well.
So in short, yes on the quest wipe and make it a full wipe to solve all problems! Winch access and factions included if they play a role in the problems, which they most likely do.
Earl, we need to teach people not to loot what they don't need .. and last I checked there are NPCs that buy quest items.
