Don't you only need to make Wood Boards for like 2-3 ranks? After that, you actually need to use them?
Pretty much yea but using this method you would need to farm much more wood boards than how many you actually need to make total because it's not anywhere close to 100% return rate on the items that make up wood boards when you defrag them. After you get through those ranks you just start using the wood boards instead yea.
