They aren't as bad as the Redridge Bridge builders, who finally finished the bridge after about 6 years. But the worst? Sentinel Hill Inn builders. 6 years and I don't think they finished it. They even built a wall around Sentinel Hill, but couldn't fix a hole in the inn's roof.
i'm sure there were people in there digging out an instance summoning stone last time i was in there... maybe they've found the rest of the dungeon by now...
