|I believe certain sets are still leased by individual players, such as Adventure, Robber, Militant, etc.. The more expensive ones. I dont think leasing a thief set will make much profit.|
Best at this moment (imo) would be investing in an adventure set (with enchants or without). During FFA you can most definitly lease those with enchants, the other one can be leased for using in the adventure guild. Those are just a few examples.
