Why no Plex system?

[Snow_Princess]

Last thing : no

It works like this:
I go mog station and buy a sub token (does not matter what means I buy it with)
I get said item in moogle mail
I sell it on MB, trade, exchange trade agreement for savage/mount deal, whatever

That's what I don't get. How would you expect to buy the sub using gils? The only fixed currency from mog is crysta.
They either allow buying crysta in-game or have an external NEW site special for subscription.

I explained it.. >< Has nothing to do with crysta, I guess you never played other MNOs?
