Deadmines is one of the most popular instances to run on the Alliance side of World of Warcraft, and probably in the entire game. It is usually tackled by five-man teams of level 18-22 characters. The instance is populated with mobs, Elites and non-Elites, between levels 16 and 22, more or less.
Deadmines is always popular because it features the conclusion — or at least an important stop — in several Alliance chain quests. The loot, especially the Bind-On-Pickup Blues, make this instance unavoidable for anyone who wants good gear but doesn’t want to pay through the nose for it at the Auction House.
