These former players are returning to complete old content, emptying bag space and completing quests to prepare themselves for the new content.
Hence, they will be putting surplus items onto the Auction House to make a quick sale without really knowing their true worth.
This is a great time to pick up those recipes you are missing, buy cheap raw materials or even cheap rare drops.
Picking up those recipes you are missing
I use Auctioneer and it only takes 20 seconds to do when you are at the Auction House.
1. Open the Auction House window
2. Click Recipes and then select the profession you are searching
3. Tick “Usable Items” on the top bar of the window
the example above shows that my the Auction House has 7 recipes (4 different ones) that my Tailor does not have though none are below my 100 gold price.
Only takes 20 seconds to do.
Hence, in a very short period of time you can go through all the items you often buy to see if there are any cheap items on the Auction House.
I do this scan at least once a day and it is a great way to pick up those cheap raw materials to craft as well as find cheap items that are normally highly priced.
