One of the best parts of Asynchronous Trade is that I can take a few weeks off from playing, and still log into a bunch of currency from items I priced a month ago.
Pretty much as stated in the title. The player run shop, or asynchronous trade, has been such a huge benefit to players, and gets me logging in after I took a break to play some other games.
Then once you realize you have a small stock pile of Divines, and looking into what upgrades you could purchase, and suddenly you are mapping again to just see how much better your character feels after buying a new weapon, etc.
