I think it would be awesome to have a dark smugglers cache reward instead of the rank points reward on the wheel. To me that is the best drop in the game and i would think more people would be prone to spend GP to try for it.

Thing is, theres alot of players out there that have or can get shed loads of GP, there will need to be a low chance as 8 hours worth of everything is rare for a reason. Have you seen the amount the high ranks have of their resources?

I would agree but It would be over-used, make it like a 5% chance or something then go for it.
