Possible market board exploit

[MsMisato]

Retainers you can put in your yard are still part of the server's marketboard so there's an amount of risk that somebody else will buy your cheap stuff.

Gear/weapon wise you can mark it sell as set and it doesn't pop on the MB all other loose non gear items you have to sell on MB or trade them to an alt and what not. Easier to sell higher level gear honestly
