It doesn't help them because they don't need it. All they need to do (and what they currently do) is to use credit card fraud or to steal accounts to have infinite supply of accounts.
You may not think it, but experience proves you wrong. In both EVE and TERA there's never shortage of offer to match the demand.Also, what do you do when your subscription runs out, and there is no scroll on AH to buy? I don't think there will be enough people willing to pay RL money for gil to keep up with the people who would rather just pay gil for their subscription.
Again, an assumption born from lack of knowledge. In other games they aren't abused (and if there's a game in which the playerbase WILL abuse any system that gives them a chance to, that's EVE), because the system is ironclad, and you can't turn the items back into real money.And finally, as we've seen time and time again: people will always find a way to exploit stuff like this. So I think it's best if we just leave it alone.
There's no reason to believe that the final fantasy XIV audience will manage where the EVE playerbase didn't in five years.
Economy doesn't work like that. With this system while a person's buying power increase, anoter's buying power is reduced, so the total buying power remains the same.
By selling to NPCs you *create* money. Devaluing money itself in the process. With this system there's absolutely no money created -> No effect on the economy.
To put it down simply, and to be bluntly honest, whoever says that this system wouldn't work here because the final fantasy audience is somehow more exploit-ready than others either never played other MMORPGs or he's simply talking without the slightest knowledge of the market.
EVE online is the largest den of scum and villany in the galaxy. Final fantasy (XI or XIV) players are like harmless kids (exploiting potential-wise) compared to a large portion of the EVE online playerbase.
The fact that the PLEX system resisted exploit in that game is all the demonstration we need that, with the proper failsafes, it's a very safe system to use.
There's a lot to be learned by observing other games. Some people around here should learn that lesson. Luckily SE seems to have learned it already with the advent of Yoshida.
