The only reason a company with stable, committed subs would decide to do this is that they are giving up on fighting RMT, and plan to BECOME RMT in order to get a slice of the pie.

Not only does this legitimize RMT, unless there are numerous special checks and balances to eliminate trading of this new product, it will be incessantly exploited.

The weddings were a one and done situation for those who wanted it. This is a market people will never stop wanting. The level of crap this will create is incredible.

PLEX system should only be in games designed to handle it. Yoshida has on multiple occasions confirmed FFXIV is not designed with plex features in mind.

PLEX, F2P, B2P, P2W, Freemium... all of these can easily be implemented. Just don't expect positive results trying to tack this onto an existing Sub-based MMO, you are risking incredible damage to the playerbase loyalty, among other issues. Quit confusing apples (EVE) as oranges (FFXIV). They aren't even close to the same type of online game.
