I have to chuckle at the memory of one of the worst quests in WoW because it offers a deadly combination of two of the gripes: nonsensically low drop rates and Murlocs. Called The Star, the Hand and the Heart, it's available to both factions; Alliance picks it up in Badlands. It involves travel to three widely-separated locations on two continents. But here's the clincher -- on an island off the coast of Dustwallow Marsh, one must grind Murlocs for a low drop rate item called Enchanted Sea Kelp. This can take anywhere from twenty minutes to two hours! The comments on this item are a hoot; my favorite:
This part of the chain can take hours and hours of mindless grinding. The droprate is so low that you can even outlevel the quest before this actually drops.On Murlocs!
