I don't see any issues with this. Sure, it doesn't seem too bright to keep trading away the same players and getting the same guys in return, but as long as the trades are relatively even, and they pay the transaction fee, then so be it. I don't see any issues with it.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
