What does cash shop do for this game?

[Remus]

I am more just curious because they have had a cash shop up for some time now and I thought when it released this will help with creating a bit more content because they have a bit more money in their pocket.

I see people spending large amounts of money on Fantasias, buying mounts, buying minions etc but since then the game hasn't changed much in terms of content. When I heard they would include more content in 3.x I thought maybe this is where the cash shop money comes in but then I saw they had to remove a dungeon for it. I think they said they used it for EU data centers but that can't be the only reason because we still have the cash shop.

So I want people's opinion on the question: What does the cash shop actually do for FFXIV?
