And your suggestion is very open ended.
Do you want the EXISTING perks to rotate, or new perks added in for rotation for specific turfs?
See, holding a turf carries over between server sessions, if I cap Panagia for Crafting discounts, then it switches to zaros perks next session, I would be dicked if I already own 2 turfs that next session.
People invest a lot of money for housing in these turfs because they want a better shot at getting those turf perks. Same as buying a house in Abdera for running scotch.
