Bank Alt is a bank character created by wow players to mail items to and store for future use or to be sold. Sometimes it is referred to asBanker or Mule but Bank Alt has become a popular term. Every Banker needs access to 4 vital things: A Bank, A mailbox, presumably an AuctionHouse, and a nearby Vendor.
To start a Bank Alt, create a character and name it something simple.
1. When you're working on dailies, you're going this way and that, and you really can't afford to blow your Hearthstone cooldown on a side tripto a capital city, this is where a bank alt comes in. Just send all your stuff to them, switch over, and throw the stuff on the AH. Also, If youhave multiple stacks of some stuff: eg Netherweave Cloth, Arcane Dust, and Greater Planar Essences, it's nice to be able to store them so youdon't flood the AH and bring down prices.
2. It is more organised so that you are able to know where to go to and find what you need and send it off to the character that need itinstantly. It can be pretty annoying if you cant find the items you need in the midst of the game.
3. Being able to mail all your estra stuff to a Bank Alt to free up space quickly. When you are in the middle of a play session and you areloaded with Motes of Mana, Arcane Tomes, Sunfury Signets and various items from the outland daily circle, just go to the nearest mailbox, sendthem to your Alt and voila, you are ready to be out for another round of farming.
4. Once your Bank Alt can hold no more, and it is almost weekend, start posting them up for Auctions!
Some players are annoyed that they have to sacrifice one slot for Bank Alt, instead of one extra Alt that they have been thinking of making, butin the long run, you will realise that having a Bank Alt is awesome. It is a great time and space management tool. The purpose of a Bank Alt isto make money.
I'd recommend that you give it a try, especially if you're a busy 70 with bag space problems. You'll be glad you did.
