Why level 5? Because then you can get Enchanting which will allow you to disenchant low level items, which can make a nice cash flow by itself. Simply put, you create the character, level it up to 5 or so, and then run it to the nearest AH where it’ll spend the rest of its career. They’re less necessary these days, but sometimes one just has too much stuff… One upon a time, before the creation of the bank a mule was a character used to store excess stuff.

It can also be called your Bank Alt (Alt = Alternate Character.)

This “mule” is just another character that you don’t bother to level up much. No, not the four legged kind, which isn’t available in WoW anyway. Yes, there is a better way than flying back to the big city after every loot run. Or do you just dump it all into the nearest mailbox and send it to your banker alt (mule) and get right back to the looting/crafting/raiding? So do you stop what you’re doing, run back to town, hope on the nearest bird-like thing, and fly to the capital city, then the Auction House, post all your stuff, and then travel all the way back to your looting fields? Or mage-port to the city and then find your way back? You’ve got a ton of sellable stuff, at least you hope it’ll sell, and it’s time to get the stuff onto the Auction House. Maybe your other alts have all the crafting skills, maxed. Ok, you have your mining and skinning skills together and you’re working them hard.
