It's time to reevaluate the idea of adding a PLEX/Chronoscroll-like system to FFXIV

[MageBlack]

SE gets the same amount of money. A months subscription time always comes from SE and always requires real money to be created, just under the proposed system you can buy more months than you need and then sell them on the market board in-game.

Ah, that's true. But unless the cost of those "CREDD/PLEX" items on the market boards can be regulated and limited to a set cost of gil, then either the players selling will end up making huge profits off this or get undercut so badly that the items become worthless as in game money.
