Maybe we need a Cataclysm

What the game needs is what they did with 1.0 to 2.0 but without sacrificing the current service. This means the company itself would have to hire more people, you know, invest in your own product and service for the betterment of it, and do this over a 2-4 year period (or however long it takes).
That, or just invest on a new FF mmo that isn't held back.

Edit: Thinking about it, how about they get Sony to invest in this kind of upgrade just like Microsoft invested in Sega for Phantasy Star online 2's substantial upgrade coming next year.
